Forms Data Controls :: Javascript Loop Through Each DropDownList Inside GridView

Mar 28, 2010

I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:

[Code]....

With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.

AJAX :: DropDownList Inside A TemplateColumn Inside A GridView Inside A UpdatePanel?

Apr 26, 2007

I have a DropDownList inside a TemplateColumn inside a GridView inside a UpdatePanel. (out of breath saying that)

I have the DDL's AutoPostBack set to true and the OnSelectedIndexChanged event set to an event in my code. The problem is when the DDL's index changes, it posts back. It does not do the UpdatePanel magic and not post the whole page back, and the OnSelectedIndexChanged event does not fire. Anyone see anything wrong with my approach?

Web Forms :: How To Validate The Length Of The Text Present In The Textboxes Of A Gridview Using Javascript

Apr 6, 2010

Can any one let me know "How to validate the length of the text present in the textboxes of a Gridview using javascript".

For Example: In a page I am displaying a Gridview with textboxes inside it and a button on the page. The user need to input some text in the textboxes of the gridview and click on "Submit" button. When the user clicks on Submit Button, we need to validate the length of the text present in the textboxes of the gridview. If the length of the text inside the textbox of the gridview is less than 10 , we need to throw an error message. In the same way we need to do validation for each and every textbox inside the gridview.

Forms Data Controls :: DropDownList Inside Of A GridView

Aug 17, 2010

I've seen several examples here but for some reason I still cant get this to work. I have a gridview of user information.

userid name phone role
00001 john 12345 [downdownlist]
00002 jack 12345 [downdownlist]
00003 jeffz 12345 [downdownlist]
00004 jims 12345 [downdownlist]

The code would look something like this:

<asp:GridView
ID="gvUsers"
runat="server"
AutoGenerateColumns="False"
DataSourceID="dsUsers"
DataKeyNames="id"

[Code].....

So as my example code above shows, I'm trying to build a dropdownlist within the gridview. The datasource for the dropdownlist is based on the userid. The two datasources (dsUsers, dsRoles) are two different tables in the database. HOw can I implement the dropdownlist to use the userid from the gridview to query the dsRoles to populate its list?

Forms Data Controls :: Dynamically Populated Dropdownlist Inside Gridview

Mar 28, 2011

I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.
