So I have a hierarchical RadGrid with 1 master table and 1 detail table.

The detail table has the property 

The TemplateForm has 1 TextBox and 1 RadAsyncTable and the submit button (insert, update).

Now when I choose a file to upload and hit "insert" the file is uploaded and everything works correctly.

The problem is that when the file exists, I want to display an error message : "the file already exists". So I have a method to verify if the file exists. If this is the case, I want to keep the EditForm opened and display the error message. But when I choose another file that doesn't exist and hit submit again, it looks like the RadAsyncUpload loses its value and the file is gone.

Here is my code:

I have a RadGrid with two date columns and I have added a Calculated Column to get the number of days between them.

I tried a couple of techniques I found from Google to display the number of days but it always displays in this format:  2.00:00:00 for two days.  Fourty days looks like 40.00:00:00.  I just want to display the number of days as an integer like, "2" or "40".

The Calculated column UniqueName="DaysOpen".

One of the techniques I tried did the calculation in the .vb file and was supposed to send the value to a GridTemplateColumn with a <asp:Label /> in the ItemTemplate, but that method didn't work at all.  The column showed no values at all.  The column was there but all the fields were blank.
.aspx


.aspx.vb  -  I commented out both methods because neither of them seemed to do anything.  In or out made no difference to the grid contents at all like they just weren't accessing the grid objects, which is probably the case.  On line 27 I hard coded a "3" in place of the now commented out, [date].ToString and the column was still blank.

With my markup and code just as above the DaysOpen column displayes the correct number of days, just in the long format.  I just want to display it as an integer. e.g. "40" not "40.00:00:00"

Thank you!

Hi,

I have a Radgrid with 2 columns freeze and I have enabled the resize columns, Am dynamically populating the grid, The problem is When the columns are more By deafult horizontal scrollbar appears and freezing works fine,But when we have less columns then columns get fixed accordingly and horizontal scrollbar doesnot appear which is correct..However for that less columns when we resize columns horizontal scrollbar appears then freezing doesnot work.
Ultimately Freezing works fine when the horizonatl scrollbar appear by default but doesnot work when we resize columns and horizontal scrollbar appear.
So is there any workaround for this?

Hi,

I have a user control in which I am using a RadTabStrip & RadGrid. On tab click I have to update the grid. 

So to ajaxify I am using RadAjaxManager as below

When I click on the tab for first time the grid gets refreshed but after that none of the tab click event fire. But when I remove "radTabStripInd" from updated controls the grid refreshes for every tab selection but radTabStrip tab does not change to selected state.

Note: If i use a RadAjaxManager on a master page and RadAjaxManagerProxy on usercontrol everything works but I see the performance issue ( 6 -8 sec to refresh the grid).

Can you please let me know how to fix this issue?

Regards,
Kalyan

Hello,
I have added custom functionality to my RadGrid to persist grid column visibility when user toggles column visibility from "Columns" context menu.
So whenever user comes back to that page, same columns are displayed as last time.

I am applying persisted settings in Grid prerender event by calling following function:
        private void ApplyGridSettings()
        {
            var persistenceHelper = new PersistenceHelper();
            var settings = persistenceHelper.GetGridPersistenceSettings(this.ClientID);
            if (settings != null)
            {
                foreach (var columnSetting in settings.ColumnsSettings)
                {
                    var column = this.Columns.FindByUniqueNameSafe(columnSetting.Column);
                    if (column != null)
                    {
                        column.Display = columnSetting.Visible;
                    }
                }
            }
        }

Now I have added a header context menu "Reset Columns" to remove persisted settings and reset grid columns to default visibility.
I am calling following code on HeaderMenu click:

        private void HeaderContextMenu_ItemClick(object sender, RadMenuEventArgs e)
        {
            switch (e.Item.Text)
            {
                case "Reset Columns":
                    var persistenceHelper = new PersistenceHelper();
                    persistenceHelper.ResetGridColumns(this.ClientID);
                    this.MasterTableView.EnableColumnsViewState = false;
                    this.MasterTableView.Rebind();
                    break;

                default:
                    break;
            }
        }

I thought after rebinding the grid will reset grid columns, but it is not working.
Can anyone please suggest how to reset grid columns visibility?

Hi,

this Telerik support page claims that I can enable WAI-ARIA support by using the EnableAriaSupport property.

But I cannot find this property on my radPanelBar ASP.NET control (see attachment).

How can I enable WAI-ARIA support for all Telerik ASP.NET controls? (I particularly need it for the TreeView control, too.)

Hello !
I use a RadSearchBox like this : http://demos.telerik.com/aspnet-ajax/searchbox/examples/overview/defaultcs.aspx.
And I search to have my result in First or a "auto-scroll" to go to my result.
I tried with onFocus and this code :  var typeSearchBox = $find("<%= RadSearchBox1.ClientID %>");
                                                          typeSearchBox = typeSearchBox.get_inputElement();
                                                           typeSearchBox.focus();

But I don't arrive. Do you have a idea ?
