Hide and unhide columns not working with Display and Visible properties.

Hi
I tried to hide and unhide columns with different option but nothing looks working with RadGrid.

1. I have a dropdown- checkbox with Column names,whose values I am storing in hashtable on button click.

protected void btnChooseColumns_Clicked(object sender, EventArgs e)

{

ht = new Hashtable();

foreach (RadComboBoxItem item in rcColumnChooser.Items)

{

CheckBox checkBox = (CheckBox)item.FindControl("CheckBox");

ht.Add(item.Text, checkBox.Checked);

}

          BindGrid();

}

Now after the BindGrid() method executed it is going to ColumnCreated event and executing as expected.

protected void rgCatalogs_ColumnCreated(object sender, Telerik.Web.UI.GridColumnCreatedEventArgs e)

{

if (ht != null)

{

if (ht.Contains(e.Column.HeaderText.ToUpper()))

{

GridBoundColumn boundColumn = e.Column as GridBoundColumn;

e.Column.Visible = (bool)ht[e.Column.HeaderText];

}

But column hide and unhide is not happening.

Thanks in Advance

DateTimePicker icon disappearing

Hi,

ran into this issue:

I have a RadGrid, with GridTemplate columns. Some of these columns have DatePicker controls in EditItemTemplate.
After I have enabled filtering and put in FilterItemTemplate RadComboBox controls, icons on Datepickers disappared and instead there was either link with text "opens the callendar control" or blank. When you are clicking on such a crippled link, a calendar pops up but its skin is lost and it looks transparant.

if I use a plain asp:DropDownList, then icons are ok, - somehow presence of RadComboBox there messes up calendar and DateTimePicker control
However if I use asp:DropDownList, then SelectedIndexChanged event is not firing , even though I have AutoPostBack="true"

Any clues?

running licensed version of controls from ASP.NET AJAX Q3 2010, VS 2010.

e.startsWith is not a function

Hi,

Good day!

I use different ASP.Net Telerik controls in every page in my project.
I'm getting this javascript error: "e.startsWith is not a function"
every time I click every where on the page.

The error is in MicrosoftAjax.js which is embedded in the page by the Telerik.
I attached here the screenshot of the error I'm getting.

Does anybody here also experienced this error? How did you fix it?

Thank you.

How to make splitter displays one pane only?

Hi all,

I want to use Splitter as a CollapsiblePanel. It means there are 2 areas on my page and I just want one area is visible at one time.
For ex :
1. As default the first pane is visible, the second pane invisible.
2. When user clicks on the Splitbar, the second pane is visible & the first pane will be invisible.
If user clicks again on the Splitbar the step "1" will be applied. When Splitbar is clicked, it will be slided from left to right / right to left depending on which pane is visible.

Thanks for your help.

Browse dialog only appear on localhost?

We have a SharePoint 2010 Visual Web part which has a RadUpload control inside a EditForm template within a RadGrid. If we are browsing the page from the server itself; the browse for file dialog opens correctly; but if we access it from any other computer the browse dialog does not appear?

We're using the latest version of the ASP.NET Ajaz controls 2011.2.712.35.

Filtering: Type 'Pair' to type 'String'

Greetings,

We have a RadGrid with filtering enabled; the page is ajaxified and includes a RadWindowManager as well.
We've been using filtering for a while now with no problem. However, here the filtering fails with an error message:

Error: Sys.WebForms.PageRequestManagerServerErrorException: Conversion from type 'Pair' to type 'String' is not valid.

Anyone has encountered this kind of error message?
The only difference from other RadGrids where filtering works without a problem is the RadWindowManagers. Is there a conflict we're not aware of?

Thanks in advance.
