Get value of GridView Cell in RowCommand

Question

I need to get the value of a cell from the RowCommand event, but the value is not in the PrimaryKeyNames parameter of the GridView.

Currently I have:

if (e.CommandName == "DeleteBanner")
        {
            GridViewRow row = gvCurrentPubBanner.SelectedRow;
            string BannerName = row.Cells[1].Text;

This doesn't work (index out of range error), I've also tried:

    int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvCurrentBanners.Rows[index];

This doesn't work either as the CommandArgument (the banner ID) is not the row ID.

Dim row As GridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)

Then get the key or get the cell and cast to a datacontrolfield.

Dim id As Guid = GridView1.DataKeys(row.RowIndex).Value

Dim email As String = CType(row.Cells(2), DataControlFieldCell).Text

Remark: this only works with Boundfields.

@Romil: your code in C#:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
    int id = (int)GridView1.DataKeys[row.RowIndex].Value;
}

(LinkButton is button in template field).

Try out this one..

GridViewRow gvRow = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
int rowIndex=gvRow.RowIndex

I dont see how that could work, as you're creating a new GridviewRow, not referencing the existing one in the gridview – Fandango68 Feb 06 '16 at 21:34

int index = Convert.ToInt32(e.CommandArgument);

It only work when you use your button in Gridview is

<Columns>   
     <asp:ButtonField ButtonType="Button" Text="Save"  CommandName="Select" /> 
</Columns>

I not sure this is correct but it work for me

This is the correct solution, as documented on the [MSDN page on `RowCommand`](http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowcommand%28v=vs.110%29.aspx): _The ButtonField class automatically populates the CommandArgument property with the appropriate index value._ – marapet Feb 10 '14 at 09:10

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Edit_Mob") {

        GridViewRow row = (GridViewRow (((ImageButton)e.CommandSource).NamingContainer);

        int RowIndex = row.RowIndex; // this find the index of row

        int varName1 = Convert.ToInt32(((Label)row.FindControl("lbl_mobile_id")).Text.ToString()); //this store the  value in varName1

        }
   }

there is missing a `)` bracket at `= (GridViewRow` in answer — , Mar 14 '18 at 13:31
