ScriptManager loads multiple Telerik.Web.UI.WebResource.axd files

I have several JS files that were linked on my site and I wanted to combine them into just one call, so, I added this to the RadScriptManager

<CompositeScript>

<Scripts>

<asp:ScriptReference Path="~/js/jquery.min.js" ScriptMode="Auto" />

<asp:ScriptReference Path="~/js/webctrl.js" ScriptMode="Auto" />

<asp:ScriptReference Path="~/js/default.js" ScriptMode="Auto" />

<asp:ScriptReference Assembly="System.Web" Name="WebForms.js" ScriptMode="Auto" />

</Scripts>

</CompositeScript>

Now, whenever I view the site, the above scripts are combines, however, the original Telerik resource file that was being loaded is now at least 2 files and sometimes 3 or more.

I have noticed that the order in which they are loading has changed. Originally, the static resources would be served first, then a single combined telerik resource file. Now, a telerik resource file is served first that contains only basic MS ajax code, then the combined static resources, then one or more telerik resource files.

I'd like to include everything into one resource file if possible, but I'm not sure that is even able to be done.

Resize pictures, Email, Save and Delete big ones

Hi,

I dont know where to start on this so thought of posting it. Basically, I have to address all the following tasks.

We have a large number of pictures which we send out to our customers on a regular basis. They get over sized and dont upload properly.

I plan to make an application which re sizes and emails pictures.

1) Select pictures with similar names ( first 5 digits) from some selected folder. May be on a button click.

2) Re-size them to 200KB-400KB.

3) Upload and Email them (Using Exchange). Email address is entered by user. Usually there would be around 20 pictures attached per email.

4) Save those re-sized pictures to some drive.

5) Delete the non-re-sized pictures which were selected.

Could you please guide me little bit on what controls can I use?

Thanks

Simple bind textbox in code behind?

I cannot find a complete example. Found tons on grid and combobox, but not textbox. This test is to lookup a “PhoneTypeName” from a UserPhoneType table with TypeCode = “0” and assign that first value to a asp.net textbox.

Currently, I am getting “Object reference not set to an instance of an object” when setting the text box to "phonetype.FirstOrDefault.PhoneTypeName.ToString"

Using dbContext As New EntitiesModel()

    Dim phonetype As IEnumerable(Of User_PhoneType) = dbContext.User_PhoneTypes.Where(Function(c) c.PhoneTypeCode = "O")

mytextbox.Text = phonetype.FirstOrDefault.PhoneTypeName.ToString

End Using

Also, would binding work any differently in this case if this were a radtextbox?

Thanks.

RadAjaxLoadingPanel now showing

I have a RadGrid inside a Panel, inside a User Control. In the RadGrid is a RadComboBox in a GridTemplateColumn. When the user selects a value from the RadComboBox it fires a postback to automatically populate the next column. The problem here is that although it fires an Ajax Request, the loading panel doesn't display. The page appears ready to use the entire time. I've tryed configuring the AjaxSettings every way I can think of. I've set the combo box as the ajax control with the grid as the updated control, the grid and the panel, the panel and the panel, every possible combination; but the loading panel will not show up. Here's the current Ajax Settings:

<telerik:AjaxSetting AjaxControlID="radGridGovernanceWithin">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="radGridGovernanceWithin" LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

Edit width of textboxes in a ragrid column, programatically at runtime.

Hello!

When I enter edit mode in a Telerik radgrid I end up with all the textboxes beeing in different width.

I thought of solving this, by looping through all the items that is beeing edited and set them to System.Web.UI.WebControls.Unit.Pixel(300); to change the size. But I am doing something wrong here, I can't get it to work? And I want to refrain from using the getColumnEditor.

I thought of using it like this: But I cannot get it to work. Any idea?

protected void radgrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

//the item is in edit mode

GridEditableItem editedItem = e.Item as GridEditableItem;

editedItem.Width = Unit.Pixel(300);

editedItem.Height = Unit.Pixel(300);

}

Any idea what to do to make them into the same size?

On a side note, a total different question, Is it possible to set .Enabled status (ReadOnly) programatically without knowing what type the column is?

At the moment I am just stuck with having to iterate through and check whether the column textbox is a GridTextBoxColumnEditor / GridNumericColumnEditor and so forth. It's annoying way to solve it.

Eg.

if (columnEditor is GridTextBoxColumnEditor)

{

GridTextBoxColumnEditor item = columnEditor as GridTextBoxColumnEditor;

item.TextBoxControl.Enabled = false;

// To hide completely item.TextBoxControl.ReadOnly = statusReadable ? false : true;

}  

else if (columnEditor is GridNumericColumnEditor)

{

	GridNumericColumnEditor item = columnEditor as GridNumericColumnEditor;

	item.NumericTextBox.Enabled = false;

	

}

See? I even have to specify NumericTextBox so I can't make generic solution to this? Anyone knows?

Sorry for having two questions in one thread, hope it is OK.

Best Regards
Nicklas

Modify Grouping Header

Hi All,
I have a grid with drag to-group enabled. One of the columns is a template field. The data coming from the DB is a binary mask which I'm "translating" in code-behind to "human-readable" format.
Everything works, but when the grid is grouped by the template field, the group header (obviously) displays the raw data (the binary mask). Is there a way to modify the header display? There's an 'OnGroupsChanging' event, but I can't find the correct property to modify.

Thx in advance.
Rgds - M.

Template Field:

<telerik:GridTemplateColumn SortExpression="MATCH" HeaderText="Match"

HeaderButtonType="TextButton"

UniqueName="Match" DataField="MATCH"

GroupByExpression="MATCH Group By MATCH">

<ItemTemplate>

<asp:Label ID="lblMatchColumn" runat="server" Text='<%# GetMatchCodes(Eval("MATCH").ToString()) %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>
