Hi
I am using an edit form template within a radgrid. My edit form template is used to update Customer records. One of the fields in my customer table is TitleID which is a foreign key to the Titles table. This table contains records such as Mr, Mrs Miss etc. The form template contains a drop down list of these titles which is populated from the database. The SelectedValue property of the dropdown list is set to the TitleID of the current record. This is achieved like so
This code works fine for automatic updates. However when i try to perform an insert I get an error binding to the drop down list
I understand what is causing this error. Naturally for an empty record the value for Bind("ContactTitleID") is an empty string whereas this is not one of the items in the drop down list of titles.
How can i overcome this whilst still performing automatic inserts and updates? I can populate the drop down list of titles and the selected value in the ItemDataBound event but then the SelectedValue property of the of the cboTitles dropdown list is not passed to the ContactTitleID field because this control is not bound to this field.
I think this problem is avoided in standard grids because they have different templates for inserts and updates.
Many thanks

Hello Telerik team,
We have discovered an issue with the RadEditor in a RadMultiPage or a RadSplitter (RadControls For Asp.NET Ajax, version 2011.3.1305.40) . In our scenario, we are attaching a click event handler to the editor as soon as it loads. The click handler fires correctly when the editor is not nested within a splitter or a multipage. We require to have the editor within a RadPageView in a RadSplitter, so please advise us on how to fix this issue.
Below there is some test code we have used:
None of the above test scenarios fire the click handler of the RadEditor. Moreover, in the RadMultiPage scenario, Google Chrome shows an error when clicking the second tab:
As a note, we have just upgraded our RadControls from version 2011.2.915 (the click handler of the editor worked fine with this version) to the latest version.
Please provide us with a solution to this problem.
Thank you.

Hello,
It would be nice to be able to display an empty text in a RadTextBox in password mode.
In the sample below, I setup a RadTextBox in Password mode (line 4) with an empty message (line 5).
Unfortunately, when the text box is displayed I cannot read the empty message since it is written as a password => I just get a series of black dots.
Does anybody has an idea to fix this?
BR, Laurent

Hi,
I am using Rad grid in my web application. I am using collections to bind it to the rad grid. i will pass values to the collection and bind it to Rad Grid for the first time if i click the button which is outside the Rad grid. When i click the button for the second time i will have a new set of records in my collection. I want this one to be added to the Rad Grid. How it can be done? Here the collection will not retain the value and so if i bind the collection to Rad Grid, i will get only the record that i have added at the last. Instead i want two record in the gird. i.e, the record that was previously in the grid and the new one that i have added to the collection during the click of the button for the second time.
One way of doing is using session or view state -- this will affect the performance which am not interested and the other is loop the grid and add it to collection and add the new records to the collection and bind it to the rad grid. Since looping is involved and as the volume of data grows, it will affect performance. Is ther any other way to accomplish this?
with Regards,
S . Surendar

I have an ItemCommand for my grid which is "RowClick", which updates a group of labels via ajax when a row is clicked.
On the PreRender event of the grid I am selecting the first row on page load, how can I fire off the "RowClick" ItemCommand?
Thanks,

I chose a filename with an underscore in the string, e.g. "Primary_menu"; and in do so, I noticed that the colors and other properties I changed--and incidentally saved--were not actually saved, but rather ignored. I thought I may be doing something wrong or a problem with Visual Style Builder was occurring. Well, it appears that by removing the underscore to: "PrimaryMenu", caused everything to save and update properly.
This is not an issue for me, but I thought I'd ask the Forum if I missed something, the Forum had in fact encountered this, or let others know that this exists and that they simply need to do as I did--remove the underscore to proceed as expected. I hope this helps others out there from losing valuable time running down this nuisance.
