In my gridview, I have an ImageButton and when the user clicks it, I show a modal, however, when I popUp modal its showing me the same Datakey value for each row, so, is there a way to use FindControl for the selected row within the RowCommand?
View 5 RepliesMay I know how can I call my "OtpLeaveDefineGridView_RowCommand(OtpLeaveDefineGridView, ??? );" at other function. I really don't know what should I put at "???" for the GridViewCommandEventArgs.
protected void OtpWebLeave_ServerValidate(object source, ServerValidateEventArgs args)
{
try
{
OtpLeaveDefineGridView_RowCommand(OtpLeaveDefineGridView, ??? );
OtpLeaveDefineDataSource.Insert();
args.IsValid = true;.........
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)

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 button field in grid view, basicly i want to show to in some of the row only, but i cant find the "ID" using find control
This is my aspx code

I have a aspx. site with a repeater and a HeaderTemp. in this i have this code.
[Code]....
my question is how do i in VB use the findcontrol from the aspx.vb (codebehind) so i can use the selected value in a if-then-else.
[Code]....
this 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?
I 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
I have a usercontrol include file that has a panel on which I have programatically added checkboxes that equate to the results of a selection via a sql select stmt.
I am now trying to find the results of the checkboxes (ie checked/unchecked) using findcontrol as per
[Code]....
the commented out code is a different attempt
Is this the correct method(s) or should I do something different
Can Someone explain why this doesn't work here, when it works in another formview?

How do I disable the DataGrid controls in ItemCommand using VB.For Example I have dropdownlist bound in my DataGrid. Now I want to Disable this control in Datagrid_ItemCommand.I tried like this
View 9 RepliesI 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:

I 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)?
Can one use the findcontrol to access the row.cells value? (C#)

I though that this would work, but alas no.
I got a content place holder, in this holder, I have a grid view. Inside this grid view, I will have multiple textbox added at runtime.
From the source code, I found that one of the textbox's id is as "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1", CPHDetail is the content place holder, and gvDetail is the grid view.
What I wanted to do is to find the text box control and retrieve its value.
So far, this is what I have done, and it was able to return the correct info up to the grid view. It can never find the text box control.
I wonder will it caused by the ct102 between "ctl00_CPHDetail_gvDetail_ctl02_txt_Text1"

now, I added information to the <headertemplate><table><tr><td>headers</td></tr></table></headertemplate>
and my label in the <itemtemplate><asp:Label id="Label1" runat="server"></asp:label></itemtemplate>
and now when I run my same code, I get [object reference not set to an instance of an object]
what gives? It was working until I added a header template.
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.
Label1.text = CType(GridView_MyAds.FindControl("ItemId")
I need this correctly done....
