Forms Data Controls :: Dynamically Populate Data Control When Dropdown Item Is Selected

Sep 3, 2010

I'm currently working on a project and I want to make as much things as possible performing on client side - with as little loading as possible. The project consist of three "main" pages. On one page I use jQuery DataTable plugin which is working great. One page has tabs (using jQuery). I want to put datacontrol (repeater) on this site and when user selects one item in dropdown, data in repeater loads on client side, without performing the action on server.

Forms Data Controls :: Change Stored Procedure When Dropdown Item Is Selected And Show Repeater?

Jul 9, 2010

I have one repeater on page which has his own sql data source. I've placed 2 dropdown lists on the page. The repeater has jQuery DataTable plugin. With 2 dropdownlist I wish to change the sql stored procedures so when each will be selected the data in repeater will change. When user select the first there will be only data (users) according to selected item and in the second the same. I wrote 2 simple functions for changing stored procedure of repeater and rebiding it. Everything works but when I try the second one and then the first I always get warning about error "Procedure or function .... has too many arguments specified".

I think that when I select the first one the second function is still called although I don't call it.

Forms Data Controls :: Listview Find Control In Selected Item?

Dec 30, 2010

i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.

To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.

To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?

Forms Data Controls :: Two Dropdown Lists That Populate Gridview?

Jul 22, 2010

I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.

My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.

Now for the problem.

User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.

I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.

What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?

Here is my code

For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:

Forms Data Controls :: Populate Dropdown List With Special Character

Nov 1, 2010

Using a gridView to read some data from a SQL database. The user can select a record in the gridview. On the SelectedIndexChanged property I populate this to a couple of text boxes & drop down list; txtCountry,ddlProvince,ddlCity.

I have special characters in France ( accent marks) and when I populate it to the drop down list it fails giving out the error message "SelectedValue which is invalid because it does not exist in the list of items".

Example of items that I try to populate are as follows. ( separated by commas) ÎLE-DE-FRANCE , PROVENCE-ALPES-CÔTE D'AZUR , RHÔNE-ALPES, DRÔME,ISÈRE ........ When I looked in the drop down lists for Province and Cities I see those Provinces there in the item list. When I debug line by line the word ÎLE-DE-FRANCE comes out like LE-DE-FRANCE which is not there in the drop down list. Got to know the Î is typed by pressing down ALT+206 and lloks like this is what is coming in at the start of the string above.

Forms Data Controls :: Populate Multiple DropDown Lists With One Query?

Jan 17, 2011

I am using a dataset control and I have 5 dropdown lists in which their content depends on what item is selected in each dropdown list.

I know I can populate the lists with 5 different queries taking the variables from each list but I am thinking there must be a better way.

Is there a way to populate each list with one query that takes the distinct items from each column returned without looping through the entire recordset?
