How to tie the need datasource delete option to Right Click Context Menu in the RadGrid

Hi,

Below is our application example URL:
http://test.aptisys.com/UOMSetup.aspx

In all our screens we are using the Right Click Context menu in the Rad Grid with Add, Edit, Delete and Duplicate in the Context Menu. We have implemented the need data source with insert, update and delete command methods. But for the delete, in our old implementation without the need datasource we used the below syntax.

         case "Delete":

                    RadGUOM.MasterTableView.PerformDelete(RadGUOM.Items[radGridClickedRowIndex]);
                    RadGUOM.Rebind();

But after implementing the Need Data source, we cant able to delete the row even we right click the context menu and delete, the delete command method is not fired. We are not sure about how to call the delete command method from right click context menu. Could you please send us some example with right click context menu by right clicking and deleting the grid data implemented with the need data source by calling the Delete command method?

Thanks & Regards

How to get text of a label on server side that is filled by javascript Client side event ?..

Hey everyone,

I have used a textbox on blur client side event to get text on to the label like this...

function show(txtQuantityE, lblRate, lblAmount)

{

var txtQuantityE = $find(txtQuantityE);

var lblRate = document.getElementById(lblRate);

var lblAmount = document.getElementById(lblAmount);

lblAmount.innerHTML = parseInt(txtQuantityE.get_value()) * parseInt(lblRate.innerHTML);

}

now i am trying to get this value of label filed by OnBlur event on server side to save it in a data Table.But its coming null.My CS is--

DataRow drValues = dtValues.NewRow();

drValues["Items"] = combo.SelectedItem.Text;

drValues["Rate"] = lblRate.Text;

drValues["Quantity"] = txtQauntityE.Text;

drValues["Amount"] = lblAmount.Text;

dtValues.Rows.Add(drValues);

dtValues.AcceptChanges();

drValues["Amount"] = lblAmount.Text;
This row is null when i debug using breakpoints.Hence,can't get this value inside my data Table.How should i do this?...

Thanks
Amit

Problem with SqlConnection on binding to Telerik Grid

Whenever I have to reboot my production server, I lose all access on SqlConnections associated with a SqlDataSource binding for the Telerik Grid for ASP.NET AJAX.

I have never been able to determine the cause of the problem. Everything works fine on my development server. Everything works fine when I move it to the production server, but then if that server is rebooted, I lose all access to those Telerik Grids and I get the error pasted below.

Eventually after waiting... and waiting... and repeating attempts to access the web page with the Grid, I eventually get a connection and data populated in the Grid. What could be causing this problem?

What is the most reliable data source to use with data binding for the Telerik Grid in ASP.NET AJAX web apps? By reliable, I mean relatively trouble free data binding without worrying about mysterious connection problems like the one I experience whenever I reboot my production server. Oh, please do not criticize me for rebooting my production server. Yes, I know that I should avoid doing that whenver possible.

Thanks.

RadInputManager with TextSetting, SetFocus does clear the Text

Hi all,

I am using the RadInputManager on a webform. I have a textbox i want to control. It must have content, so, I have set the TextBoxSettings attributes like this:

EmptyMessage="type.." Validation-IsRequired="true"

If I click the textbox, the "type.." text disappears, and I can type in my content - no problems.
But when I want the cursor to be in the control set in page load, the "type.." text remains, and when I type "123 " in the box, it gets like this: "123 type..". And it's with the gray "disabled" look.

I have tried to write the javascript my self, in stead of using the Page's SetFocus method. Same behaviour occures.

Any one having experience with this issue?

Kind regards
Morten

Radlistview not binding correctly during rebind

Hello ,

I'm facing problem with rebinding RADListView from code behind by changing the databasourceid in the event of RADTreeNode selection.

I'm desiging a page with Radtreeview and Radlistview and while clicking the node on the RADTreeView I'm getting the directory path from the treenode and assigning the selected directory to the RADListview in the code behind to list all images.

Intermittently the RADListView is not getting the correct path and binding to a previously assigned values. This is happening more frequently.

I'm displaying the same treenode selected path on a Gridview and that is showing the correct values for that selected treenode consistently. It seems to be an issue with the RADListview binding using AJAX.

Is there an alternate approach I can try to fix this dynamic biding issue? Thanks for your help.

protected void RadTreeView1_Selected(object sender, RadTreeNodeEventArgs e)

{

if (e.Node.ToolTip == "Album")

{

string albpath = "";

if (RadTreeView1.SelectedNode.GetFullPath("/") == "Sample Folder/Sample Album")

{

albpath = "~/" + "Registered_Users_Uploaded_Images" + "/" + RadTreeView1.SelectedNode.GetFullPath("/");

}

else {

albpath =

"~/" + "Registered_Users_Uploaded_Images" + "/" + uname + "/" + RadTreeView1.SelectedNode.GetFullPath("/");

}

ObjectDataSource1.SelectParameters[

"path"].DefaultValue = albpath;

// ObjectDataSource1.SelectMethod = "GetData()";

RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadTreeView1, ObjectDataSource1);

RadListView1.DataSourceID =

"ObjectDataSource1";

RadListView1.Rebind();

RadAjaxManager1.AjaxSettings.AddAjaxSetting(RadTreeView1, RadListView1);

}

}

============== ObjectDataSource=============

<asp:ObjectDataSource runat="server" ID="ObjectDataSource1" SelectMethod="GetData"

TypeName="uploadWebApp.DataProvider">

<asp:Parameter Name="path" DefaultValue="~/Registered_Users_Uploaded_Images\dsnap1\My Albums\2010-10-16"/>

</SelectParameters>

</asp:ObjectDataSource>

=============================================

============ AJAX settings ==================

<telerik:AjaxSetting AjaxControlID="RadTreeView1">

<telerik:AjaxUpdatedControl ControlID="GridView1" />

<telerik:AjaxUpdatedControl ControlID="ObjectDataSource1" />

<telerik:AjaxUpdatedControl ControlID="RadListView1" LoadingPanelID="ListViewPanel1" />
