Adding Control(checkBox) in RadGrid

[Dip]

I Have a RadGrid with some field null and some field boolean Value...I have to add control in cetain Cell of RaDGrid....
Protected void RadGrid1_ItemDataBound(object sender,GridItemEventArgs e)
{
     if(e.item.is GridDataItem)
         {
                    DataRowView Rv=(DataRowView)e.Item.DataItem;
                    (Now ...)

          }
}

Till Now I can Access Row of the Grid..Now I have to Access Cell so that I can add control
eg: cell.control.add(CheckBox)..some like this...

Thanks,
DIP

Hello,

You can try out the following code to add a control to a cell based on a condition. Cells can be accessed by using the column UniqueName property for columns.

cs:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            CheckBox check = new CheckBox();
            check.ID = "CheckBox1";
            //if condition is met then
            dataItem["ColumnUniqueName"].Controls.Add(check);

        }
     }

Thanks
Princy.

that is COOL...

But is there a better way of doing it.....What I was looking for is to come up with column indexes rather than column name ...
If there a a way Please have a sample code on this post...


thanks,

Hi Dip,

Try adding the CheckBox to the desired cell as shown below.

CS:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem dataItem = (GridDataItem)e.Item;

CheckBox check = new CheckBox();

check.ID = "CheckBox1";

// check for the condition

if (e.Item.Cells[2].Text == "MyText")

e.Item.Cells[2].Controls.Add(check);

}

}

Using indexes to access individual cells in the Cells collection of a row is not a reliable method of obtaining a cell in a particular column.
The index of individual columns can change on the client on  column reordering and grouping.The reliable way of locating the cell in a particular column
is using the UniqueName property of a column.

Thanks
Shinu.

Thanks ..

Well, that still doesn't solve my problem...Let me brief it to you and may be you can give me a better solution...I am freaking out..
I have a DataTable that is in this structure..
Resource          View        Modify      
------------------------------------------
Network             true          false
Revenue                           false
Status               false        

Network             true          false


which I bind to RadGrid ..Place where states "true" I need a checkBox with checked .."False" needs CheckBox with unchecked and null is Label...I am checking this on DataItemBound using the idea stated by you..But the only reason i wanted it to do with index was because I have about 16 columns.....How can I iterate and just do it once?

Now the user can check and uncheck the checkBox...Which is also ok.... now the problem comes when use Click a button and I have to update all the checkboxes...
1) I have to Access each cell in the RadGrid + header("View/Modify") +Col1(Network/Revenue/Status) to update in datatable
2) I don't seem to find checkbox in the cells...
-----------------------Used-----------------------
RadGrid Grid=this.FindControl("RadGrid1") as RadGrid;
Grid.Cells[1].Findcontrol("Chk") as CheckBox;  (I don't seems to find CheckBox)..


Thanks,
A ton....DIP

Hi Dip,

One suggestion will be use GridTemplateColumn with a CheckBox in its ItemTemplate and bind its DataField to 'View' /  'Modify' . You can set the View / modify field as the DataKeyName and depending on its value you can set the  Checked/Visible property of the CheckBox in the ItemDataBound event.

ASPX:

 <telerik:GridTemplateColumn UniqueName="View"  HeaderText="View"  DataField="View" >
      <ItemTemplate>
          <asp:CheckBox ID="CheckBox1"    runat="server" />
      </ItemTemplate>
    </telerik:GridTemplateColumn>

//To set the DataKeyName

<MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="View"    >

CS:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            CheckBox chkbx = (CheckBox)item["View"].FindControl("CheckBox1");
            string key = item.GetDataKeyValue("View").ToString();
            if (key == "True")
                chkbx.Checked = true;
            else if (key == "False")
                chkbx.Checked = false;
            else
            {
                //to hide the CheckBox when the value is null
                chkbx.Visible = false;
                //to add a label
                Label lbl = new Label();
                lbl.ID = "Label2";
                lbl.Text = "Empty";
                item["View"].Controls.Add(lbl);
            }
        }

    }

//to access the CheckBox in the Button click event.

protected void Button1_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            CheckBox chkbx = (CheckBox)item["View"].FindControl("CheckBox1");
        }

    }

Thanks Shinu,
I can't use that because DataKeyValue is related to one column and to access other value I have to connect to database again...
Anyway I figured out a way which is primitive, but works like a charm....

Got the numver of item and got the number of cells..
Item represents -- Row
cells represent ---Column
then I iterate with 2 for loops..
RadGrid1.MasterTableView.Items[Row_Index].Cells[Column_Index].Text....

But Thanks for all the replys

Thanks,
DIP

Hi Dip,

I would like to let you know that you can set more than one field as the  key value in the DataKeyNames array.

ASPX:

<MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="View, Modify"    >

Shinu.

You see ..You should have given this hint long time ago....I implemented exactly the way you told me and is pity good in Shape...

thanks,
