Hi all,

I have a gridview there I placed some bound field and also added an image button in the last column of the grid as template field.

What I want is when I click on the image button my page should redirect to a new page with one of column values, say the id of the row where I clicked.

I can use session or query string for redirecting but how to get the row values?

I tried in many ways but I get a null reference error.
I'm unable to get the selected row using an image button.

How can I code the image button to select a row and get its values?
Please help me.
Thanks in advance...

go to selection changing event and write the code below:
Selection changeing Event

int index=gridvview.selectedindex;
session["id"]=(gridview.rows[index].cells[0].text).tostring();

in this way you get all your cell's values from selected row

sharmarun solution is if i may say, is the standard way to get your row index. There are 2 informations not clear thought. This code goes in the OnSelectedIndexChanged event. And you have to add the event in the markup : <asp:GridView ID="GridView" Runat="server" OnSelectedIndexChanged="yourSelectedIndexChangeEventName" AutoPostBack="True"/>
AutoPostBack must be set to true, to allow a post back when the selected row is changed.

Try exploring more on this MSDN Article[^].

Basically, you need to get the index of the row where the button is located. You can then get the specific row using that index:

GridViewRow row = ContactsGridView.Rows[index];

You can then get the content of the column that you want, for example:

String s = row.Cells[2].Text;

The variable s will have the value of third cell of the selected row (where your button was clicked) of you gridview.

There is an example on the link I shared.

One way is to add Click event for that image button and get the row as,

GridviewRow gvRow = (sender as ImageButton).NamingContainer as GridviewRow;

and then access the DataKey or ID which you want to pass.
PS: Code is not tested.

Alternatively you can use RowCommand.

Set the DataKeyNames of the grid view of the column name (say the ID from the DB which is in the Result set).

Now in the SelectedIndexChanged event handler writ the following code

SQL

int selectedIndex = GridView1.SelectedIndex;
string customID = (GridView1.DataKeys[selectedIndex]["pkCityId"]).ToString();
//now write Ur custom logic for creating the URL and redirecting to the
//new url

simple isn't ???:cool:

For clarity the name of my Gridview is GridView1 and the DataKeyNames (the column which actually holds the ID value) is pkCityID.

Set commandArgument like this

XML

<asp:ImageButton ID="ibtnEdit"  runat="server" CommandArgument='<%# Container.DataItemIndex+1 %>' />

then in gridview rowcommand event

VB

dim intRow as integer = CInt(e.CommandArgument)

then by using that row number u can get the row values

VB

gridview.Rows(intRow).Cells (0).Text

On image button click

GridViewRow selectedRow = ((ImageButton)sender).Parent.Parent as GridViewRow;
        ImageButton imageButton = (ImageButton)selectedRow.FindControl("imgBtn");
          if (imageButton != null)
          {
            //add your logic here
          }

Hi Friends!

Here's a way to get the values of each cell in a Grids' row (in case of binding data from code).
Consider a Button Field ('Select') in this case and give its CommandName to Select
Write in Row_Command event

C#

if (e.CommandName == "select")
 { 
  //code here
}
