Hi Developers,

I am facing the following issue regarding comparing my gridview certain column data with checkboxlist item text.

I have a checkboxlist which has only 6 items.
A
B
C
D
E
F

When the gridview is populated from database and the 3rd column i-e: Cell[2].Text has the string values of A, B, C, D, E or F. Whenever it is being populated I have to disable the items of that checkboxlist which has same values like gridview cell[2].

For example if I have A, C, E, F in Gridview cell[2] then the Checkboxlist item A, C, E, F should be enable = false;

as I have created the following method for Page.Load Event.

C#

private void EditMode()
    {
        foreach(GridViewRow gvRow in GridView3.Rows)
        {
            Label userID = gvRow.Cells[2].FindControl("Label4") as Label;

            for (int k = 0; k < CheckBoxList1.Items.Count; k++)
            {
                if (CheckBoxList1.Items[k].Text == userID.Text)
                {
                    CheckBoxList1.Items[k].Enabled = false;
                }
            }
        }
    }

Please Help.. :)

- If i understood correctly,if you have A in first Row,B in second row...F at 6th Row,then? Whole List would be disabled or what?
- check box list is part of a gridview or what?

Checkbox is out of Gridview. you are right 1st row has A, 2nd B and 3rd C so the first 3 checkboxes should be disabled in the checkboxlist control.

C#

protected void GridView3_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowState != DataControlRowState.Edit) // check for RowState
        {
            if (e.Row.RowType == DataControlRowType.DataRow) //check for RowType
            {

                foreach (ListItem c in CheckBoxList1.Items)
                {
                    if (c.Text == userID.Text)
                    {
                        c.Enabled = false;
                    }
                }
            }
       }
    }

and to retain the checkboxes statuses whether checked or not

C#

protected void GridView3_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        DataTable dt2 = ViewState["DatainEditMode"] as DataTable;
        int index = Convert.ToInt32(e.RowIndex);
        if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[0].Text.ToString())
        {
            CheckBoxList1.Items[0].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[1].Text.ToString())
        {
            CheckBoxList1.Items[1].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[2].Text.ToString())
        {
            CheckBoxList1.Items[2].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[3].Text.ToString())
        {
            CheckBoxList1.Items[3].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[4].Text.ToString())
        {
            CheckBoxList1.Items[4].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[5].Text.ToString())
        {
            CheckBoxList1.Items[5].Enabled = true;
        }
        dt2.Rows[index].Delete();
        string task_no = ((Label)GridView3.Rows[e.RowIndex].FindControl("LBL_TASKNO")).Text;
        tskctrl.deleteTaskNoDetail(task_no);
        GV3DataBinding(lbl_pTask.Text.ToString());
    }
