Dealing with converting empty string value to Integer

Hi,

With the textboxes in a RadGrid, it is possible to deal with an empty string value, that needs to be stored to an Integer value?

I am assigning a texbox to a Integer variable, though that textbox can be blank:

Dim

CodEnd As Integer? = TryCast(edit("CodEnd").Controls(0), TextBox).Text

The variable CodEnd will then be used as parameter to pass into an UPDATE SQL query.

I tried setting ConvertEmptyStringToNull="True" in the textbox, though I still got the following error:

Conversion from string "" to type 'Integer' is not valid

Any advice please?

Thank you, Ida

I have to click twice to expand nested RadGrid

I have a nestedviewtemplate radgrid inside another RadGrid. I am having a problem with the nested RadGrid not expanding on the first click. What I mean is, I expand an item in the parent grid, then when I try to expand an item in the nested grid within the parent item, I have to click expand twice. In some versions of IE, the nested grid disappears altogether after clicking expand on the nested grid just once. In IE10 and the latest version of Firefox, it stays, but just doesn't expand until the second click.

Has anyone else experienced this and found a solution?

Thank you in advance. Below is my markup.

Skin disappears

Hi there,

I have the following scenario that I need to implement:
1. Generate a pdf-file (serverside). This will take me about 10 seconds server-side
2. Send file to browser

While the file is generated, I need to display something to the user. I am currently using the Radnotification control for this.

My problem is:
While the file is generated the notification control loses its Skin. I have tried different approaches to solve it, but with no luck so far.
It is important to consider, that the generated pdf-file is sent to the by writing to the Response-object, which is not allowed when the trigger lies within an update panel.

I suspect I must be missing some fundamental knowledge of the Telerik controls and hope you can guide me in the right direction. Below is my code.

RaisePostBackEvent causes DetailTables expansion to fail

Hey all,

I am having trouble getting my DetailTables expansion to work with a RaisePostBackEvent that I use for my OnRowClick event in my RadGrid.

When I have a RaisePostBackEvent in my code behind, my row expansion for my DetailTables does not fire, but if I simply comment out the RaisePostBackEvent code block it works just fine.

Any ideas? I can't find anything about it anywhere.

Thank you!
Dan

How do I add content to tabs, server side?

Requirements
RadControls version
.NET version 4
Visual Studio version 2012
programming language C#
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION
I am trying to create a tab in the code behind with contents, I can create tabs fine but don't know how to assign something to it (the content) I can't even figure out how to do it client side, but usually in normal AJAX you would do it like tab.controls.add(control) but in the telerik version it adds the control to the actual tab rather than the content.

Issue with Page Refresh (F5) after creating an Event

Hi,

We are having a problem with the RadScheduler. After creating an Event (it doesn't matter if its just a single or a recurring event...), when you press F5 to refresh the page, another event is created... basically a duplicate of what you just created.

I wonder if this is a bug or am just missing something (i.e., needs to declare something, etc...). Below are the step-by-step detail in recreating the issue:

1. From the Calendar, double click on a date to create an event. (NOTE: As I have indicated above, it doesn't matter if its a Single or Recurring event because the results are the same.) Once the event is created, it will show up on the Calendar.
2. Click on the browser's "Page Refresh" button or "F5"... you will notice that a duplicate event is created.

What should we do to prevent this issue from happening?

Thanks for your help.

RadTreeNode newNode = new RadTreeNode();

newNode.Text = obj.NAME;

newNode.ToolTip = obj.NAME;

newNode.Value = obj.ID.ToString();

newNode.DataItem = obj.ID_LAYER;

newNode.NodeTemplate = new TreeNodeTemplate(obj);

RadTreeNode parentNode = rtvSearchResult.FindNodeByValue(obj.ID_FOLDER.ToString());

if (parentNode != null)

{

parentNode.Nodes.Add(newNode);

}

{

rtvSearchResult.Nodes.Add(newNode);

}

}

public void InstantiateIn(Control container)

{

Label control = new Label();

control.ID = "lbn_" + _obj._ID;

control.ClientIDMode = ClientIDMode.Static;

control.Text = _obj._NAME;

container.Controls.Add(control);

Label lbButtons = new Label();

lbButtons.Text = "<input type='button' value='1'/>";

lbButtons.ID = "node_" + _obj.ID + "_cmd";

lbButtons.ClientIDMode = ClientIDMode.Static;

container.Controls.Add(lbButtons);

}
