Forms Data Controls :: Findcontrol In A Gridview / Give The Controls Unique IDs
Sep 14, 2010
I've got a gridview with a few textboxes in each row which I want to insert into a database, after a user clicks a submit button (thats outside of the gridview)
This is my code for the gridview
[Code]....
And this is my code for the button
[Code]....
But when I click the button it gives me this error
"Multiple controls with the same ID 'Label12' were found. FindControl requires that controls have unique IDs."
How do I give the controls unique IDs if they are in a gridview and the rows are database driven?

I have a user control, which is added dynamically, but I have noticed that when it is on the page and viewing the source that none of the controls within have been given unique ids. How do I give my user control and the controls within unique ids in order that I can use them in my events?

I'm doing this in my Master Page. I want to access a Linkbutton within the Gridview and set the enabled = false; I tested this and it works all the way up to the first if statement.If I insert a response.write to get the frmctrl.ID, I get all of the controls on the page. BUT, can't get the controls within the gridview.How do I get the contorls within the gridview? I prefer not to do this using Findcontorls and esp setting the control to Public.

I have a dynamic gridview in which i need to add textbox, checkbox, imgButton in the cell dynamically.
At the moment user click on the imbgutton, a click event fire and i need to capture the user input on the checkbox and textbox of the particular cell.
I have problem in finding out the checkbox and textbox control in the imgbutton click event. The cause is i do not know which row in the gridview i need to search to for the control.
I have try gridview.Fincontrol but fail.

using the GridView FindControl.
What I've done is I've setup a Gridview with a datasource to show only 1 of the columns I need from the datasource, but I also have another ItemTemplate Column in which I have a dropdownlist with another datasource that I've bound to the dropdownlist.
What I need to do is have the dropdownlist show the selected one when compared to a id from datasource in the gridview.

I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.

In my GridView I use FindControl/<FooterTemplate> with a TextBox that you can enter an integer with a comma
into the TextBox, because I create an instance of the Textbox first and then remove the comma out of the integer before the TextBox is used to update the table in the database.
However once the data is in the table and displayed in the GridView if you try to change the integer and use a comma in the GridView you cannot because FindControl/<EditItemTemplate> will not create an instance for you to remove the comma from the integer before it updates the table because FindControl/<EditItemTemplate> doesn't allow you to create an instance of the TextBox first, instead when you try to use the instance that looks like was created it gives an error stating:
Object reference not set to an instance of an object.
So the question is:
HOw do you create an instance of a TextBox in a GridView when using FindControl/<EditItemTemplate>?
