How to Set Paging

[DEBAL]

Hi Support

In Radgrid for asp.net , I have large number of records in Grid and there is radio button along side with every row , I also use paging and page size = 20, now how can I know which row number will be if radio button number choose by user  or suppose selected RadioButton is 80 then how can i show the radgrid paging in that page where the radiobutton is existed . By default paging starts from 1 but I need to show that page where user choose may be the page is in 8th number paging ,

See the code:
Private void Method(int number)
{
RadGrid1.Allowpaging = false;
 RadGrid1.ReBind();

 foreach (GridDataItem item in grid1.Items)

 {

  RadioButton btn = (RadioButton)item.FindControl("radiobutton1");

  string value = item.GetDataKeyValue("Questionnumber").ToString(); 

    if( value == Questionnumber)
          {
                 btn.checked = true;
RadGrid1.CurrentpageIndex = questionnumber;
}
RadGrid1.Allowpaging = true;
RadGrid1.PageSize = 20;
 RadGrid1.ReBind(); // if I write this then my Radio Button selected is not show and if I not write then paging is not show

Any suggestion will be helpful or any demo project

Hello DEBAL,

Please check below code snippet.

// By below code you can set pahe number 8 on button click
    protected void Button1_Click1(object sender, EventArgs e)
    {
        RadGrid1.MasterTableView.CurrentPageIndex = 3;
        RadGrid1.Rebind();
    }

Hi
Thanks for your reply , you write is through hardcoded but I need like that

Private void Method(int number)
{
RadGrid1.Allowpaging = false;
 RadGrid1.ReBind();

 foreach (GridDataItem item in grid1.Items)

 {

  RadioButton btn = (RadioButton)item.FindControl("radiobutton1");

  string value = item.GetDataKeyValue("Questionnumber").ToString(); 

           if( value == Questionnumber)
          {
                    btn.checked = true;

RadGrid1.MasterTableView.CurrentPageIndex = 3;

// see ,here is also one problem : I write it 3 but it should be like that
// which radiobutton is selected I need to find the current page Index of that page where the selected radiobutton row is exist .
// suppose I know in Current pageIndex 3 , my desired item row is exists so I write this , so the paging will be selected in 3 but I need
// to do it though code , any Idea pl

        int pagesize = RadGrid1.PageSize;

        RadGrid1.Rebind();


        foreach (GridDataItem item in RadGrid1.Items)
        {
            count++;

            if (item["ID"].Text == "7")
            {
                break;
            }
        }

        double temp = count / pagesize;
        int temp1 = Convert.ToInt32(count) / pagesize;

        RadGrid1.AllowPaging = true;
        RadGrid1.MasterTableView.CurrentPageIndex = temp == Convert.ToDouble(temp1) ? temp1 - 1 : temp1;
        RadGrid1.Rebind();

    }
