Hi all,

 I have a nested grid view, in which child grid is below(like collapse and extend) the parent one.

Now in child gridview has columns with id as datakey , image button,etc.

When i clicked in a image button in child grid i want to get the row id,

Can some one help me ? 

Try:

protected void ImageButton1_Click(object sender, EventArgs e)
{
        ImageButton b = (ImageButton)sender;
        GridViewRow row = (GridViewRow)b.NamingContainer;
        if (row != null)
        {
             int rowIndex = row.RowIndex;
            //do something 
        }

} 

 Hi,

Globally declare your child GridView as follows

GridView childGrid;

In ParentGridviews DataBound event find out the childGrid control

as follows :

 protected void ParentGrid_RowDataBound(object sender, GridViewRowEventArgs e) {
        if (e.Row.RowType == DataControlRowType.DataRow) {
            childGrid = (GridView)e.Row.FindControl("childGrid");           
        }
    }

 protected void childGrid_RowDataBound(object sender, GridViewRowEventArgs e) {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string rowid = childGrid.DataKeys[e.Row.RowIndex].Values[0].ToString();
     // use this rowid for your further process of code.
 }
}

hope this may help u.

Thanks vinz, Bur i am getting an error while using that row value.

string

error::

Object reference not set to an instance of an object.

Can u help me further to get that grid view row?

             int rowIndex = row.RowIndex;
             //Get the DataKey value
             string key = GridView1.DataKeys[rowIndex].Value.ToString();
             //Get the Row value of BoundField
             string rowValue = row.Cell[0].Text;

The how to get the child gridview id, Because it is nested inside the  Item Template..

 hi,
you can write as follows :

 protected void btn1_Click(object sender, EventArgs e)
    {
       foreach(GridViewRow row in ParentGrid.Rows){
        	childGrid = (GridView)ParentGrid.Rows[row.RowIndex].FindControl("childGrid");   
	   	foreach(GridViewRow row1 in childGrid.Rows)
        	{
                	int code = Convert.ToInt32(chilGrid.DataKeys[row1.RowIndex].Values[0].ToString());                     
			// write your code here whatever u want
        	}
	}
    }

I hope this may help u.

sir according to ur code child grid will correspond to the last trow of main grid not the one that i am desired,

Because child grid can be of any main row...

Hi gaurnitai,

You have a ImageButton in the child GridView, you want to get the id of the clicked row in this child GridView, right. Then you can bind CommandArgument to ID field and handle its Click event to get:

<asp:ImageButton runat="server" ID="ImageButton1" Text="Check" CommandArgument='<%# Eval("ID") %>' OnClick="ImageButton1_Click" />

protected void ImageButton1_Click(object sender, EventArgs e)
    {
        string id = ((ImageButton)sender).CommandArgument;
        GridViewRow gvr = (GridViewRow)((ImageButton)sender).Parent.Parent;
        int row_index = gvr.RowIndex;
    }

Thanks,
