get datakey value outside of radgrid event

[ranro]

I was wondering if someone could explain to me how to get the datakeyvalue of a selected row on the server side and outside of a radgrid event. 

For instance say I have a radgrid and it has a row that has been selected.  When someone clicks a button (called btnTest for instance) that is somewhere else on the page, how do I go about getting the datakeyvalue of the selected row in btnTest’s click event.

Hi Ranro,

Try the following code snippet to achieve the desired scenario.

ASPX:

<ClientSettings >
   <Selecting  AllowRowSelect="true" />
 </ClientSettings>
<MasterTableView  DataKeyNames="CustomerID"    >

CS:

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

Thanks
Shinu.

How can I get the selected row's datakey value using js on client-side?

 I have already found this snippet in the help file:

 

var firstDataItem = $find("<%= rgGrid1.ClientID %>").get_masterTableView().get_dataItems()[0];

 

 

var keyValues = firstDataItem.getDataKeyValue("unique_id");

This does not get SELECTED row's data key, only first row.

I need to get this outside of a radgrid client-side event as well.
thanks.

Hello Kel,

Please examine the approach shown below:

function buttonClick()
{
    var radgrid = $find('<%= RadGrid1.ClientID %>');
    alert(radgrid.get_masterTableView().get_selectedItems()[0].getDataKeyValue("OrderID"));
}

Hello,

     

<MasterTableView  DataKeyNames="ID" >

protected void btn1_Click(object sender, EventArgs e)
    {
        Button btn1 = sender as Button;
        GridDataItem item = btn1.NamingContainer as GridDataItem;
        string ID = item.GetDataKeyValue("ID").ToString();
    }

Let me know if any concern.

Hello Francis,

You can try the following method to access ClientDataKeyValues in onclick event of LinkButton.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
    GridDataItem item = (GridDataItem)e.Item;
    LinkButton link = (LinkButton)item.FindControl("LinkButton1");
    int rowindex = item.ItemIndex;
    link.Attributes.Add("onclick", "clicked('" + rowindex + "');");
 }
}

Javascript:

function clicked(rowindex)
{
   var row = $find('<%= RadGrid1.ClientID %>').get_masterTableView().get_dataItems()[rowindex];
   alert(row.getDataKeyValue("ID"));//DataKeyName
}

Thanks,
Princy.

Thanks Princy

This Fantastic Code just bailed me out

protected void getAcceptRequest_Button_Click(object sender, System.EventArgs e)
{
LinkButton butAccept = (LinkButton)sender;
GridDataItem editItem = (GridDataItem)butAccept.NamingContainer;
HiddenField hfRequest_Id = (HiddenField)editItem.FindControl("hfRequestId");
string requestId = hfRequest_Id.Value;

HiddenField hfRequest_From = (HiddenField)editItem.FindControl("hfRequestFrom");
string requestFrom = hfRequest_From.Value;

HiddenField hfRequest_To = (HiddenField)editItem.FindControl("hfRequestTo");
string requestTo = hfRequest_To.Value;

runAccept(requestId, requestFrom, requestTo);
}

I appreciate!

Hi,

Please try setting the DataKeyNames property of the MasterTableView as given below.

ASPX:

<telerik:RadGrid ID="Rad" runat="server" AllowFilteringByColumn="true" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" >
    <MasterTableView DataKeyNames="OrderID,ShipName">
         . . .
    </MasterTableView>

Thanks,
Shinu.

Hi Princy,

I couldn't get the DataKeyValue at client side using RoeIndex.

var r=$find('<%= Rg_Centers.ClientID%>').get_masterTableView().get_dataItems()[index];
            alert(r.getDataKeyValue("CenterId"));

the above code gives null value.

[Princy]

Hi Thangarai,

Please make sure you have set the ClientDataKeyNames for the Grid.

ASPX:

<MasterTableView ClientDataKeyNames="CenterId"  DataKeyNames="CenterId">

Thanks,
Princy

Thanks Princy,

Can anyone help me out how to assign row.KeyValues["TestGuid"] to TestGuid.Value.It is not working with migrated RadGrid to Asp.Net Ajax.

After migrating from Classic RadControls ,It stopped working and throwing error , can anyone help me what should be replaced in that case.

Here is the Code ,

<div style="display:none">	    
        <asp:Button ID="btnSelect" CausesValidation="false" runat="server" OnClick = "btnSelect_Click" />
	    <input type="hidden" id="hidType" name="hidType" runat="server" />
	    <input type="hidden" id="hidGuid" name="hidGuid" runat="server" />
	    <asp:Button ID="btnRemove" CausesValidation="false" runat="server" OnClick = "btnRemove_Click" />
	    <input type="hidden" id="hidCheck" name="hidCheck" runat="server" />
	    <input type="hidden" id="hidRemove" name="hidRemove" runat="server" />
	    </div>

Javascript Code for the selected Row for RadGrid:

 function TestItemRowSelected(row)
    {
        var TestGuid = document.getElementById('<%= hidGuid.ClientID %>');
        var showType = document.getElementById('<%= hidType.ClientID %>');
       TestGuid.value = row.KeyValues["TestGuid"]; ---->Issue 
        showType.value = "Test";
        var oButton = document.getElementById("<%=btnSelect.ClientID%>");
        oButton.click();
    }

Error :
