< br $> b $ b

What i want to do is to assign a textbox dynamically created from a table cell into a gridview row button clicked.This is what i have done so far.Any help will be appreciated.

protected override object SaveViewState()
{
    var viewState = new object[2];
    //Saving the dropdownlist value to the View State
    viewState[0] = txtmonday.Text;
    return viewState;
}

protected override void LoadViewState(object savedState)
{
    //Getting the dropdown list value from view state.
    if (savedState is object[] && ((object[])savedState).Length == 2)
    {
        var viewState = (object[])savedState;
        //var count = int.Parse(viewState[0].ToString());
        CreateDynamicControl();
        base.LoadViewState(viewState[1]);//cheged from 1 to 0
    }
    else
    {
        base.LoadViewState(savedState);
    }
}


public void CreateDynamicControl()
{
    var txtmonday1 = new TextBox();
    var textboxCell = new TableCell();
    var tableRow = new TableRow();
    tableRow.Cells.Add(textboxCell);
    textboxCell.Controls.Add(txtmonday1);
    tbl.Rows.Add(tableRow);
   // txtmonday1 = (TextBox)txtmonday1;
   // int count = GridView1
   // GridView1.Controls.Add(txtmonday1);



}

protected void btnupdate_Click(object sender, EventArgs e)
{




    foreach (TableRow row in tbl.Rows)
    {
        var textbox = row.Cells[0].Controls[0] as TextBox;
    }





}



protected void btnedit_Click(object sender, EventArgs e)
{

   // txtmonday.ID = "txtmonday1";
    int index = GridView1.EditIndex;

    Button btn = (Button)sender;


    GridViewRow gvr = (GridViewRow)btn.NamingContainer;

    int getindex = gvr.RowIndex;


    string id = GridView1.Rows[getindex].Cells[4].Text;



        TextBox txtmonday = new TextBox();
        txtmonday.ID = "Textbox1";
        string get = GridView1.HeaderRow.Cells[3].Text.ToString();


        txtmonday.Text = GridView1.Rows[getindex].Cells[3].Text;
        Page.Form.Controls.Add(txtmonday);
        GridView1.Rows[getindex].Cells[3].Controls.Add(txtmonday);

}

推荐答案

如果你想在特定单元格中使用txtbox意味着放置文本框在gridview里面的griditemtemplate中，所以当编辑完成后，显示txtbox而不是itemtemplate关联控件

If you want the txtbox in a particular cell means put the textbox in the edititemtemplate in the table which is inside the gridview so when editing is done the txtbox gets displayed instead of the itemtemplate associated control
