Forms Data Controls :: How To Use The GridView FindControl
Jan 6, 2010using 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.

Forms Data Controls :: FindControl Failed To Work For GridView
Nov 8, 2010I 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.

Forms Data Controls :: Create An Instance Of A TextBox In A GridView When Using FindControl?
Dec 28, 2010In 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>?

View 5 RepliesForms Data Controls :: FindControl To String?
Feb 9, 2011this is probably very simple but I'm tearing my hair out!I'm using the FindControl method to try and grab the text in a textbox inside a DetailsView Template Field and display it on a label. Here is my code:
[Code]....
The word text has a squiggle underneath though and it causes an error as "System.Web.UI.Control' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)". I know the problem is that I'm treating this Control as a TextBox when it isn't, it's a Control. So how do I get from Control to TextBox so I can take the String and use it in code?
Forms Data Controls :: Assigning Value Using FindControl?
Jul 23, 2010I thought I had this all figured out, in fact the following is similar to another page I have that works, but dinged if I can see what is wrong with this.I have a FormView with the InsertItem Template as the default. I have a label "UserId" that is assigned the logged on user's userid on page load with:
LblUserID.Text = Membership.GetUser.ProviderUserKey.ToString , which I am certain works.
There is a textbox "User_IDTextbox" within the InsertItem Template of a FormView, and I am trying to write the UserID into that text box using this VB code in a subroutine:
Dim TxtBxUserIDParent As TextBox = DirectCast(FVAddTradeResort.FindControl("User_IDTextbox"), TextBox)
TxtBxUserIDParent.Text = LblUserID.Text
This does not result in populating the textbox within the InsertItem Template of the Formview template with the UserID

View 9 RepliesForms Data Controls :: Getting Databaound Control Using FindControl?
Mar 18, 2011I have a form with a basic FormView control. The FormView is set to Edit mode by default with only two textboxes and one button. I am populating the FormView using a Datatable from the code behind generated from a SQL Stored Procedure.
The data fills the FormView just fine. I am attempting to update the data using a SQL Stored Procedure by getting the values from the textboxes in the FormView on button click Everything seems to work and I recieve no errors, however the values I type into the textboxes is not passed to the stored procedure so eventhough there are no errors the data is not updated.
I know that the issue is not my stored procedure becasue if I use static values for the parameters in the code behind, the values are updated by the stored procedure.
I placed two plain textboxes and a button on the ASPX form and create a button click event for that button using the same code I use for the butten click event in the formview. When I add values to the non-databound textboxes, the data is updated correctly.
The question is, why can I not get the updated/changed values from textboxes in the FormView control?
Here is my ASPX code:

Forms Data Controls :: Using FindControl On Nested FormViews?
Sep 3, 2010I have a nested FormView and I need to get the values from some of its controls (TextBox) in code behind.
I can easily pull the values from the "parent" FormView using:
TextBox txtBox = (TextBox)fvParent.FindControl("txtField");
String myStr= txtBox.Text;
Although, when I try to get a refence to one of the controls in the "child" FormView I get a null. I am trying to do this:
FormView formView = (FormView)fvParent.FindControl("fvChild");
TextBox txtBox = (TextBox)fvChild.FindControl("txtChildField");
String myStr= txtBox.Text;
The variable "formView" is set to null. Can the FindControl method not find nested items? If not, what is the proper way of getting the values from these fields (in the Child/Nested FormView)?
