Populate Dropdown Box From SQL In Web Matrix?

Jan 22, 2004

I have been attempting to populate a dropdown (combo) box from a SQL query (SQLConnector) in Web Matrix and I have so far been unsuccessful. I have been able to populate a DataGrid just fine from the query, so then I limited it down to one colum (so itd be in the dropdown box) and set all the properties I could find (DataSource, DataMember, DataTextField, DataValueField) (and in all possible combinations) for that dropdown box to the SQL stuff (SQLConnector for the DataSource and then used the dropdowns for the others), and nothing shows up in my dropdown box. How can I make this populate off of my SQL query properly?





Additionally I will need to do the same thing for a Checkbox List so if it is the same and you know how to do that and could let me know for that too that'd be great.





Thanks a million in advance!

How To Populate Table From Dropdown List?

Oct 18, 2005

Hi,I have table (tbl_a) that get it values form three Dropdown List and the PK of this table is FK in different table(tbl_b).Since tbl_a get its values from three Dropdown List the number of rows in this table is limited to the number of combinations the three Dropdown List is offer (in any case the number of raws in that table will be final).Assuming tbl_a and tbl_b are both empty.
The problem is that if i want to insert row to tbl_b i have to check first if there is a row that holds the values (or combination of values) i am getting from the Dropdown List in tbl_a .Then, if such row is exist i have to get the PK of that raw and insert it to tbl_b (as FK),if such row does not exist, i have to insert it and then get the PK of this row and insert it to tbl_b (as FK).
In the end, tbl_a will have all the combination the three Dropdown List can offer so checking if raw exist in this table will not be necessary.
In my opinion this is not effective way to do that.Can someone offer me better way to do it?
Thanks

Populate Dropdown List With Dimension Hierarchies

Dec 17, 2006

Hi,

I am currently trying to develop an application which would help in retrieving data from cubes (Microsoft Analysis Services)! The user would not be accessing the Business Intelligence Studio, etc. but would be viewing the data from a custom made application developed in VB.Net2005.

While implementing this, I want to populate the drop-down-list in the VB(.Net) Form, by retrieving the various hierarchies in the dimensions of the cubes (along with dimensions if possible). This should be done dynamically and in real-time!

Can you please help in implementing this? Any code/method, etc would be highly appreciated!

Thanks in advance.

Best wishes!

(Software : SQL Server 2005 Enterprise Edition (with Analysis Services and BI Studio), VS.Net 2005 Enterprise Edition, ADOMD.Net)

Reporting Services :: SSRS Matrix - Add A Column In A Matrix With A Variance

Aug 6, 2015

I got the following code to add a column in a matrix with a variance:

IIF(IsNothing(Previous(Sum(Fields!Amount.Value))) or Fields!year.Value=First(Fields!year.Value,"Category") or Previous(Sum(Fields!Amount.Value))=0,nothing,
(
(Fields!Amount.Value)
/Previous(sum(Fields!Amount.Value))
)
)

This code works fine, except that the first row of the matrix shows an #error

This happens with each matrix where I use this expression. A warning emerges:

rsruntimeerrorinexpression the value expression for the textrun Textbox43.Paragraphs[0].TextRuns[0]' contains an error.

Attempted to divide by zero.

The strange thing is that the part

Fields!year.Value=First(Fields!year.Value,"Category")
should prevent an error and I expect it to show 'nothing'

An screenshot of the table. (each color is a different category. Each row stands for 2013, 2014, 2015)

As you can see, all other 2013 rows show a blank cell, except the first row.

A Matrix Above Two Charts. Right Chart Moves Depending On Matrix Growth ... ???

Jan 10, 2008

I have a Matrix table that expands to the right when choosing an amount of months to be shown. Under this matrix I have to Charts. The two charts are situated together, that is no space between them, and to the left of the report.

Now, if I choose a lot of months, say three years the matrix diagram will be huge to the right. The problem I have is that the second diagram, the one on the right, moves to the right depending on how big the report gets, and this is not good at all. The two charts are supposed to be all the way to the left.

How? Why does the right chart move?

Thanks in advanced
Kind Regards

Dropdown Other Options..how To Store?

Jun 2, 2005

Hi
Often we come across a form with a dropdown list (populated from a lookup table) with "Other" option as well. When user selected "Other" option a textbox appears where he can specify new option(This option is not to be added to master lookup table).

What is the best way to store it in database?
I have 2 columns (A and B). 'A' contains Lookup ID if some option other than "Other" is selected, else 'A' has NULL and 'B' field contains the text of Textbox.

But while reporting I face problems as in a report the selected option text (either 'A' or 'B') has to be shown under one column only but SELECT A,B results in 2 columns.

US / CANADA States Organized For DropDown--HELP????

Oct 30, 2004

I feel real bad asking this...but I have a state table...ordered by State ASC
and it mixes US and Canada, of course. I want to set up a table and a
stproc to produce a dropdownlist that looks like this (as I've seen in many
websites' state tables):

United States --
Alabama
Arizona
...
Canada --
Alberta
...

...and so on, so that the country is listed as a heading with no state code value
and the states each appear in asc order under the country heading. I don't know
how to do this. Does anyone have a good example of how to do this?

Thx much,

Adjusting Parameter Dropdown Width

Oct 25, 2007

Hi there,
May be a kind of dumb question, but I have a multi-value parameter that I would like to give users the ability to select from in a SSRS 2005 Report and I was wondering if there was a way to adjust the width of the drop down so the user wouldn't have to scroll horizontally to see a full parameter item. It looks like it cuts off after about 30 characters.

Any help here would be appreciated.

Thanks!

DropDown Filter In Report Builder

Jan 10, 2008



Guys,
In my report builder when I drag the SKU in the filter area, its doesnt give me the dropdown and show me the distinct values, it just gives me a text box and expects me to type in the SKU.
I have other attributes whcih have the same property as SKU but they all work fine when I drag them into Filter area.

Is there a limitation in reporting svcs where if the Field has more than "n" number of distinct records it will not populate the dropdown, instead just present you with a text box?

My DataModel Table has around 110K records and roughly 7K distinct SKU's

I compared the SKU field to other fields in the Report Model Designer and also DataSource View and nothing seems to be out of normal to not show the dropdown with distinct values except for the # of distinct records.

Appreciate your help in advance

Width On Multivalued Dropdown Menu

Nov 28, 2007

I have a multivalued drop down menu that isn't wide enough to display the entire label. It only displays about half of the label. The text it is trying to display should look like "Global Zone 1 - Global Zone 2 - Global Zone 3 - Global Zone 4", and the only visible text is "Global Zone 1 - Global Zone2". It does have a scroll bar at the bottom, but it is ridiculous.

When I set it to not be multivalued, the drop down menu grows to the size of my label. The menu has plenty of space to grow, it is only taking up a very small amount of the screen.

Is there any way to correct this issue?

Thanks

Parameter DropDown List Grayed-out

Dec 12, 2007



I am building a report with several search parameters; three of which are dropdown boxes each populated by a data set. I wanted something more user-friendly than the default "(Null)" in the dropdown, so for each data set, it returns a result set UNIONed with " N/A" to show up first as the default.

For some reason, when the report loads, the first dropdown populates just fine and does indeed have the default value " N/A" but the other two dropdowns are grayed-out. Until you change the first dropdown (to anything, apparently it doesn't matter what you change it to) the other two stay grayed-out. When the first is changed, the other two are populated and default to the desired " N/A" default value.

Why would it do this, when it didn't do it before; i.e. when the default for all of them was simply null. The dropdowns are not dependent on each other; they don't depend on other parameters for their values. Any help would be appreciated.

Special Characters In A Dropdown List

Nov 2, 2006

I have a web form that needs to be bilingual. It contains several dropdown lists. The "text" and "value" for each item in the dropdown list is retrieved from a database. The logic reads the database and then populates the various dropdowns with logic such as:

dim newItem as new ListItem(textString, valueString)

theDropDown.items.add(newItem)

The problem that I am having occurs when the textString needs to contains special characters such as accented vowels or an "n" with a tilde. I have tried populating the database with HTML-formatted strings such as "Avi&oacute;n", hoping that this would display "Avion" with an accute accent over the "o". Unfortunately it displays "Avi&oacute;n".

How do I get dynamically-created dropdowns to display special characters? If the answer is to simply store the special characters directly in the database, then the question becomes how do I get the special characters into the database? I tried to figure out how to write a T-SQL command such as

update tablex set SpanishName = 'Avion' where id=999

but I can't figure out the syntax to insert an accented 'o' into the string.

Thanks.

Adding Columns To A Matrix Report That Don't Belong To The Matrix Columns Groups

Jan 2, 2007

Can we do this?



Adding more columns in a matrix report that don€™t
belong to the columns drilldown dimensions€¦



That is, for example, having the following report:

Product Family


Product

Country City Number of units sold





Then I
would add some ratios, that is, Units Sold/Months (sold per month) and other that
is the average for Product Family (Units Sold/Number of Product Family), for putting an example€¦ some
columns should be precalculated prior to the report so do not get into it, the
real problem I don€™t see how to solve is adding one or two columns for showing
these calculated column that doesn€™t depend on the column groups but they do
for the rows groups€¦




Any guidance
on that?


The only
way I am seeing by now is to set it as two different reports, and that is not
what my client wants€¦






Many
thanks,
Jose

Separate Dropdown List Selectedvalue Into Two Fields

Aug 1, 2006

i have two columns in a "release" table that i concatenate on my aspx page into one value for my dropdown list.  for example, my database columns might look likeMajor: 3 | 3 | 4 | 4 | 5Minor: 1 | 2 | 1 | 2 | 1and my drop down list text like3.1 | 3.2 | 4.1 | 4.2 | 5.1my question comes when trying to take the drop down list's selected value and splitting it back into two fields so that i can use it for another query.  how can i split my "major" and "minor" version numbers back up so that i can run a query similar to:SELECT * FROM [Version] WHERE (([Major] = @Major) AND ([Minor] = @Minor))but only having the one parameter of: <asp:ControlParameter ControlID="ddlVersion" Name="Version" PropertyName="Text" Type="String" /> where the selected value has a string of "<major>.<minor>" (where the numbers are separated by a period)?

Updating Grid View That Has Dropdown Lists

Jun 28, 2007

I have gridview bound with SqlDataSource control. One of the grid columns is a dropdown list which is populated programatically, (the gridview has template column with edittemplate field with dropdown list), dropdown Value contains of course collection of IDs.Please tell me how to declare UpdateCommand which will update the row with the dropdown list. The problem is with parameter regarding the column with dropdown list. When i declare this parameter and bind it to SelectedValue property of the dropdownlist from edittemplate tag - it doesnt work, because datasource control cannot see this dropdown list. So, how am i supposed to declare the ID of the row being updated in <updateParameters>? Thanks in advance!
