There is code here that shows how you access controls inside of gridviews etc

i did this using following code
Label txt = (Label)GridViewUser1.Rows[0].FindControl("postLID");
string test = txt.Text;

but now problem is various data is bound to iteam template. when i used this it will give an last iteam template label value. I want the value from those which is currently access by user

How do you define what is "currently accessed by the user"?

Kishor-KW 11-Apr-16 8:05am

i am using iteam template. so all the data from the database is bind with gridview.
which contain 1]image in imagecontrol 2]name in label control 3]Id in label control.

so it will access all this value in one row. if values are three then it will show three image control and label controls representing the values at perticular row in gridview.

now let us assume gridview having three rows. Let us called those three rows on output window as layers, so it will show three layers each contain one imagebox control and two label control.

when I use following code
Label txt = (Label)GridViewUser1.Rows[0].FindControl("postLID");
string test = txt.Text;

it will only show Id of label at zero th row i.e. zero th layer.
if i want to get Id of second row which i currently access by using button click event. how to do this?

Add a command event to the button

<asp:TemplateField>
<itemtemplate>
<asp:Button ID="ButtonSelect" CommandName="Select" CommandArgument="<%#Container.DataItemIndex %>" Text="Select" runat="server" OnCommand="ButtonSelect_Command" />
</itemtemplate>

And in the code-behind

protected void ButtonSelect_Command(object sender, CommandEventArgs e)
{
int index = 0;

if (int.TryParse(e.CommandArgument.ToString(), out index))
{
// process row
}
}

hi...thanx its working. please would you explain it what actually performed by
CommandName="Select" CommandArgument="<%#Container.DataItemIndex %>

and
int.TryParse(e.CommandArgument.ToString(), out index))

If you have 10 rows in your gridview you have 10 select buttons, so to distinguish what the buttons do you have a CommandName and CommandArgument you can set. We're setting the commandname but not really using it, but we set the commandargument to be the index of that row (0, 1, etc). In the Command event of the button the commandname and commandargument of the specific button clicked is passed into the event arguments. So the TryParse just converts the CommandArgument into an int variable we can then use to access the appropriate row.

if i want to get it on page load then how to do this

F-ES Sitecore 18-Apr-16 10:47am

Go through the Rows using FindControl after the gridview has been bound as per the code in the link in the solution.

Kishor-KW 18-Apr-16 10:49am

where should to add CommandArgument="<%#Container.DataItemIndex >"I mean to which control

Kishor-KW 18-Apr-16 10:54am

is my question worng?

Kishor-KW 18-Apr-16 10:58am

i am asking this because if I used protected void ButtonSelect_Command(object sender, CommandEventArgs e) then control is only available over there I cant get access it in other function.

F-ES Sitecore 18-Apr-16 10:59am

If you go through the rows using FindCommand you don't need the CommandArgument stuff, that's just for if you click a button on the row.

Kishor-KW 18-Apr-16 11:04am

but i want to click on any one button from buttons in mutiple rows. and then only to operations with it.

F-ES Sitecore 18-Apr-16 11:19am

You can only click on button at a time, and if your code runs off of a button click you shouldn't be using the page load event to process it, but use the commandargument mechanism instead.
