Hello,

someone knows how to only disable the automatic filtering operation
when performing a filter on a row?

I need to filter a DropDown Column - so i just want to modify the gridview datasource selectcommand

It works - but just the first time and then i get this error
No property or field 'filterExpression' exists in type 'DataRowView' - its because my row is a DropDown

At the gridviews ItemCommand Event im using this code

if (e.CommandName == RadGrid.FilterCommandName)

{

gvUser.MasterTableView.FilterExpression = ""; //tried with this ... but does not work

Pair filterPair = (Pair)e.CommandArgument;

//string s = filterPair.First + ", " + filterPair.Second;

TextBox txtFilterTextBox = (e.Item as GridFilteringItem)[filterPair.Second.ToString()].Controls[0] as TextBox;

string filterValue = txtFilterTextBox.Text;

srcGv.SelectCommand = "SELECT * FROM [Table1] WHERE [ID] IN (SELECT [ID] FROM [Table2] WHERE [someRow] LIKE '%" + txtFilterTextBox.Text + "%') ORDER BY [someRow]";

gvUser.Rebind();

}

i think i just have to disable the automatic filter operation but i cant find where i can disable it ...

Greetings - Raimund

Object reference not set to an instance of an object problem

Hi,
I'm having problem with my project. Randomly, i got object reference problem in different pages, however i can't find a scenario which causes this. It's totally random.

When i catch this in debug mode, i saw that viewstates were loosing their values but i'm not sure about that. Debugger stops at a random viewstate, says value = null, however i'm sure it had a value before. Somehow, it looses its value after postback but as i said, i can't create a scenario

Here is my error log

Image path problem

Hi,
My application images folder is ~/Images
and the rad editor is in a file that has the heirarchy: ~/Admin/pageedit.aspx
When I insert any image and see its html it becomes <img src="/images/abc.jpg" .... >

I want that the image path should be shown as <img src="images/abc.jpg"...>

I have tried this and almost done on OnClientCommandExecuting using javascript. The path shown becomes OK but the image is shown as broken, as the image path becomes wrong (i.e. abc.jpg has relative path "../images/abc.jpg").

Can you help me about this problem?

[Solved] RadInput Edit and Display Value Mode Toggle

Is there a way with the RadInput textbox control to allow for users to toggle the editing and displaying of a value? What I mean is, on the load of the page, text is displayed. When the user clicks on the text, it becomes editable (i.e. text displayed within the RadInput textbox). Save and Cancel buttons are also displayed when the "edit mode" is toggled on.

Flickr does this, for example, with the naming of their photos and with descriptions.

RadEditor Image Manager - Incorrect File size from ViewPath folder

I attached a ViewPath to an instance of RADEditor's ImageManager. The tool was able to view the image in the folder, however, it is noting a file dimension (1800px by 2689 px) in the Properties tab that does not exist for the current image (100 px by 150 px). The file size in the center pane is around 6 KB, which is accurate. Any thoughts for why or where ImageManager would be storing this information? I want for it to just show the image as it exists. Thank you.

Grid hierarchy color around detail tables

I have a radgrid with hierarchy of one parent table and 3 detail tables all at the same level. When the user expands all 3 child levels at once, I set a caption to separate them. I would like to change the background color(where the caption is and around that). Not the grid background. Is there a way to change this color?

Also, is there a way to add a little space between the bottom of the last part of the child and the next parent record?

Thanks

[Solved] Enabel/Disabel Toolbarbuttons

Hi,
How can toolbarbuttons in RadEditor be enabled and disabled according to current selection. RadEditor is using toolsfile for configuring the toolbarbuttons. The sample from documentation for "OnClientSelectionChange" trying for example to enable/disable "InsertRowAbove" button does not work.

function OnClientSelectionChange(editor, args) {

var selElem = editor.getSelection().getParentElement(); //return the currently selected object in the content area

var oTool = editor.getToolByName("InsertRowAbove"); //get a reference to the custom tool

if (selElem.tagName == "TD") //if the selected element is of image type, make the tool's icon active

{

oTool.setState(0); //Enable Tool Icon

}

else {

oTool.setState(-1); //Disable Tool Icon

}

<telerik:RadEditor ID="RadEditor1" runat="server" Skin="Default" OnClientSelectionChange="OnClientSelectionChange"

ContentAreaMode="Div" Height="600px" Width="700px" ToolsFile="~/Admin/Form/Controls/DefaultTools.xml">

What is wrong I need help. Thanks.

Regards,
Michael
