I have button1 and label1.
DbGrid:
Container,
FirstName

Is it possible to find the number 3 and display data inlabel1 firstname3?
I have GridView and a button inside its ItemTemplate
<asp:Button ID="btnSend" runat="server" OnClick="btnSend_Click" Text="Отправить"
ValidationGroup="mesGr" CommandName="Send" rowId=<%# Container.DisplayIndex %> replyTo='<%# Eval("Sender") %>' />
As you can see I want to pass Container.DisplayIndex to handler. The problem is that this is not just child od ItemTemplate - Button is a child of LoginView which is a child of a Panel inside ItemTemplate ) I found a way how to pass that Container.DisplayIndex: <%# (Container.Parent.Parent.Parent as GridViewRow).DataItemIndex%>
<asp:Panel ID="pnlFocusAreaPanel" runat="server" GroupingText="Focus Area" Width="800">
<table cellspacing="0" cellpadding="0" width="750">

i want to know how i find the datakeyvalue on checked event because updateQuery in checked event is generating exception.
I have a gridview with a linkbutton in each row. When I click the linkbutton it should update the status of a field from enabled to disabled. I am using a stored procedure to achieve this but i need to pass in a ApplicationID which i am retrieving from the gridview through the use of datakeynames. I am using the code below to get this value into a variable.
iAppID = gvApplications.DataKeys(gvApplications.SelectedIndex).Values("iApplicationID")
However when it runs it gives me the following error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I add a gridview into a accordionpane in a accordion. And I bind data to this gridview and define a column as a datakeyname and make it un-visible. However when I get the datakeys[index] in the behind code, there is an error that "Index was out of range".But I am sure the index is not out of the range, and when i debug i see the count of the datakeys is 0
I don't know why this error happens?

View 1 RepliesI'm using a Gridview with Paging enabled. Also i'm using the Datakeys in Gridview. I can able to get the DataKeys values on first page. But when i click on the second page, i'm not able to get the DataKeys values. How to get the DataKeys values on Paging.
View 5 RepliesI've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.
Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.
Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.
Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.
After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.
Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.

When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.

a FormView that is linked to SqlDataSource1a Repeater control (inside the formview) that is linked to SqlDataSource2Thus representing a simple "1 to many" or "parent/child" relationship in the database!qlDataSource1 is simple in that it just retrieves a straight set of records from a table and they are displayed back in the FormView (nothing special happening there).SqlDataSource2 has parameters that filter the contents of the repeater based on the record that is shown in the Formview. This would normally be simple enough to set up by setting the parameter to the formview.selectedvalue property.HOWEVER - THE PROBLEM ARISES...The formview has multiple DataKeyNames because the table that the SqlDataSource1 links to has a compound key. So to filter the Repeater correctlySqlDataSource2 needs to map 3 parameters to 3 data key values in the formview.Any ideas how to do this?I've tried setting the SqlDataSource2 parameters to:
<SelectParameters>
<asp:ControlParameter ControlID="FormView1" Name="Parameter1" PropertyName="DataKey(0)" />
<asp:ControlParameter ControlID="FormView1" Name="Parameter2" PropertyName="DataKey(1)" />

I did that....now I want to hide / skip steps in the wizard depending on the condition of checkboxes (chkblood, chkurine,chkstool,chkmalaria)
but I cant get the value from these non-primary datakeynames...
Back in my vb.net days, I had a gridview, that when a user clicked a select button in a templatefield, I could determine the row that the user selected. Trying to do the same in C#, but am lost in translation somewhere as it throws this error when trying to get the value. This is what I have, but it throws an error.
