[Swapnil]

Hi,
how to add checkbox column in radgrid and get ids associated with that record on button click event?
Thanks

[Princy]

Hi Swapnil,

I guess you want to add a GridCheckBoxColumn.Please try the below code snippet,which shows how to add GridCheckBoxColumn ,and access the checked rows using the datakey value.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" >
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridCheckBoxColumn UniqueName="GridCheckBoxColumn" DataField="IsTrue">
            </telerik:GridCheckBoxColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" Text="Save" OnClick="Button1_Click" />

C#:

protected void Button1_Click(object sender, EventArgs e)
   {
       foreach (GridItem item in RadGrid1.MasterTableView.Items)
       {
           GridDataItem dataitem = (GridDataItem)item;
           TableCell cell = dataitem["GridCheckBoxColumn"];
           CheckBox checkBox = (CheckBox)cell.Controls[0];
           if (checkBox.Checked)
           {
            string value = dataitem.GetDataKeyValue("OrderID").ToString(); //Access the checked row using DataKeyNames
           }
       }
 }

I am not able to check the checkbox ,looks like just read only
Thanks

[Princy]

Hi Swapnil,

If you use GridCheckBoxColumn,it will be disabled in view mode.It is enabled only in insert or edit mode.If you want to check in view mode,you can use a GridClientSelectColumn,or you can add a checkbox in GridTemplateColumn.
To access the GridClientSelectColumn,please try the following code snippet.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowMultiRowSelection="true">
    <ClientSettings Selecting-AllowRowSelect="true">
    </ClientSettings>
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" />
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:

protected void Button1_Click(object sender, EventArgs e)
   {
       foreach (GridItem item in RadGrid1.MasterTableView.Items)
       {
           GridDataItem dataitem = (GridDataItem)item;
           TableCell cell = dataitem["ClientSelectColumn"];
           CheckBox checkBox = (CheckBox)cell.Controls[0];
           if (checkBox.Checked)
           {
             string value = dataitem.GetDataKeyValue("OrderID").ToString();
           }
       }
  }

Thanks,

Hello,

If you want to use @princy's code then try with the below code snippet.

protected void Button1_Click(object sender, EventArgs e)
   {
       foreach (GridItem item in RadGrid1.MasterTableView.Items)
       {
           GridDataItem dataitem = (GridDataItem)item;
           if (dataitem.Selected)
           {
               string value = dataitem.GetDataKeyValue("OrderID").ToString();
           }
       }
   }

Note : please use Item.selected inplace of checkbox.checked.

Hi Swapnil,

Make sure that you have no postback,if so please set it inside the condition if(!IsPostBack), because in case if there is postback always the default value of the checkbox will be taken,which is false.
Please let me know if any concern.

Thanks,
Princy

The second example worked fine for me, but since I see comments that there was an issue and a follow-up, I will test some more to make sure.  But everything looks find for me.

Hello,

Please try with the below code snippet.

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource">
    <MasterTableView DataKeyNames="ID">
        <Columns>
            <telerik:GridBoundColumn DataField="Name" UniqueName="Name" HeaderText="Name">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn>
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" />
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

   {

       dynamic data1 = new[] {

       RadGrid1.DataSource = data1;

   }


   protected void Button1_Click(object sender, EventArgs e)
   {
       foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
       {
           CheckBox CheckBox1 = item.FindControl("CheckBox1") as CheckBox;
           if (CheckBox1 != null && CheckBox1.Checked)
           {
               string strKey = item.GetDataKeyValue("ID").ToString();
           }
       }
   }

Your example of obtaining datakeys of selected items only returns a single value.  I would like to see an example of storing the selected values in comma separated string??

[Jayesh Goyani]

Hello Krishtopher,

Could you please elaborate your scenario and share your code what have you tried?

Thanks, Jayesh Goyani

[Kristopher]

Thank you for responding.  I have a radgrid with a checkbox column (template column) of records that i want to select and save each selection that contains a unique recordID ("CN") into a comma separated string that can be stored into a session variable that i can retrieve elsewhere.   I adapted your suggested snippet that you posted on 12 Aug 2013 but it only saves one value?  I need all the selected values in my column "CN" saved, either separated by a comma or space or however.   This is what i got so far but it is not working.

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
           {
               //GridDataItem dataitem = (GridDataItem)item;
               CheckBox chk = (CheckBox)item.FindControl("CheckBox1");
               if (chk.Checked)
               {
                   string value = item.GetDataKeyValue("CN").ToString();
                   string items = string.Empty;
                   foreach (ListItem i in chk.Items)
                   {
                       if (i.Selected == true)
                       {
                           items += i.Text + ",";
                       }
                   }
                   Response.Write("selected items" + items);
               }

[Kristopher]

I got this to work, in case anyone wants to know

string items = string.Empty;
foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
{
    CheckBox chk = (CheckBox)item.FindControl("CheckBox1");
    string value = item.GetDataKeyValue("CN").ToString();

    if (chk.Checked)
    {

        items += value + ",";

    }


}
var list = items.TrimEnd(',');
Session["mySelection"] = list;
