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]....
I have a label control inside of repeater and I can't seem to get FindControl to locate the label inside of the repeater or even the repeater itself. I'm not sure what I'm doing wrong here. OnItemDataBound is firing because "hello1" is being written but if I put anything inside of the For Next loop of rptMarketFundamentals, nothing is run inside of it.
<asp:Repeater id="rptMarketFundmentals" runat="server" DataSourceID="dsMarketFundamentals" OnItemDataBound="rptMarketFundamentals_ItemDataBound">
<asp:Label ID="lblOwnershipCategory" runat="server" Text='<%# Eval("OwnershipCategory") %>' />
</asp:Repeater>
Sub rptMarketFundamentals_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs)
Response.Write("hello1") 'this works
Dim dataItem As RepeaterItem
For Each dataItem In rptMarketFundmentals.Items
Response.Write("hello2") 'this does not work
Dim lblOwnershipCategory As Label = CType(dataItem.FindControl("lblOwnershipCategory"), Label)
If lblOwnershipCategory.Text.ToLower = "family firm" Then blOwnershipCategory.CssClass = "highlight"
End If
Next
End Sub
protected void Page_Load(object sender, EventArgs e)

got an example of a repeater inside a repeater (dataBound) code behind?
View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
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

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 Repliesthis 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'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
I am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

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?

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.
