problem regarding check box in gridview

[Shubhib]

sir, i'm using ASP.Net 2.0,
i'm using a gridview in a form and i want to create a check boxes dynamically in each row of my grid view so that i can select multiple values from that grid, i want to use those selected values for some manipulation in the same form.

foreach (GridViewRow row in GridView1.Rows) {
if (((CheckBox)row.FindControl("CheckBox1")).Checked == true) {
((CheckBox)rows.FindControl("CheckBox1")).Text();
}
}
}

u have to use row command event to achieve this functionality.

First add this code on the .aspx file to add checkboxes to GridView

Then locate

protected void gv_RowDeleting(object sender, GridViewDeleteEventArgs e) for your GridView and place the code below.

// Looping through all the rows in the GridView
foreach (GridViewRow row in gv.Rows)
{
CheckBox checkbox = (CheckBox)row.FindControl("chkDeleteRows");
//Check if the checkbox is checked.
if (checkbox.Checked)
{
// Pass the Row ID to the DeleteList function
DeleteList(Convert.ToInt32(gv.DataKeys[row.RowIndex].Values[0]));
// DataKeys should be defined in the GridView property on the aspx page along with the delete button handler like this (OnRowDeleting="gv_RowDeleting")
// DataKeyNames="ROWID" (this should be the Primary Key in the table.)
}
}
