Lazy Loading Problem to Save Selections of Telerik Grid

Hi,
Could you please address the following issue.

I have been using a Telerik grid which will load data on deman, i have created one stored procedure in db which will returns
data based on grid page size,start index and max rows. But when i go to first page and select 2 records and if i click on pag2,
so i will be loading data once again and by sending page index is 2 and page start index is 11 and max rows are 10. So if i come back to page1 then i want to select previous 2 records automatically.
so please provide me the best approach to resovle this issue.

in brief my problem is.... i want to save selections of grid rows when i load data on deman(Lazy loading)
Thanks in advance.

custom markpoints

Hi, I am have a point chart, and i want each point on the graph to be different,
So for example i have the following table of data

Name        Value

I don't want to have a legend showing, so for each point, i need a different symbol and a the name next to each point.
Is that possible??

I have included my code below

Scroll to Item

Hello,
i use a RadGrid in a UpdatePanel. The cells contain ImageButtons.

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<telerik:RadGrid ID="RadGrid1" runat="server" Width="900px" Height="400px"

Skin="Office2007"

onitemdatabound="RadGrid1_ItemDataBound"

onitemcommand="RadGrid1_ItemCommand" GridLines="None" >

<ClientSettings>

<Scrolling AllowScroll="true" UseStaticHeaders="true" FrozenColumnsCount="1" SaveScrollPosition="true"/>

</ClientSettings>

<MasterTableView TableLayout="Auto" />

<HeaderStyle Width="100px" />

</telerik:RadGrid>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="RadGrid1" EventName="ItemCommand" />

</Triggers>

</asp:UpdatePanel>

Code:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

Label lbl = new Label();

lbl.Text = item[""].Text.Substring(item[""].Text.IndexOf("|") + 1);

item[""].Controls.Add(lbl);

for (int i = 0; i < gruppenliste.Count; i++)

{

ImageButton imgbtn = new ImageButton();

if (item[gruppenliste[i].ToString()].Text.StartsWith("0"))

{

imgbtn.CommandName = "add";

imgbtn.ImageUrl = "../img/cancel.gif";

item[gruppenliste[i].ToString()].Controls.Add(imgbtn);

item[gruppenliste[i].ToString()].HorizontalAlign = HorizontalAlign.Center;

imgbtn.CommandArgument = item[""].Text.Substring(

0, item[""].Text.IndexOf("|")) +

"|" +

item[gruppenliste[i].ToString()].Text.Substring(

item[gruppenliste[i].ToString()].Text.IndexOf("|") + 1);

}

else

{

imgbtn.CommandName = "del";

imgbtn.ImageUrl = "../img/ok.gif";

item[gruppenliste[i].ToString()].Controls.Add(imgbtn);

item[gruppenliste[i].ToString()].HorizontalAlign = HorizontalAlign.Center;

imgbtn.CommandArgument = item[""].Text.Substring(

0, item[""].Text.IndexOf("|")) +

"|" +

item[gruppenliste[i].ToString()].Text.Substring(

item[gruppenliste[i].ToString()].Text.IndexOf("|") + 1);

}

When I click a ImageButton, then the grid in the UpdatePanel is refreshed.
How can I automatically scroll back to the current row/column (ImageButton) after the refresh?

Showing a panel dynamicly then fill a combobox that is inside the panel

Hello !
I'm a beginner with Telerik and ASP.NET.
I would like to do something I know it is possible but I can't understand how it works.

I work with VB.NET. I have a page with code behind.
In my page, the first time it is displayed, I want to show only
- a telerik:RadTextBox
- and an asp:ImageButton

What I would like to do is :
When the user write some text in the radtextbox then click on the ImageButton, I want to execute in the code behind of my page, some

code with an sql query and then, if with the sql query I find in my databases the value the user has written in the radtextbox, I

would like to show a panel (just change its property VISIBLE=FALSE to TRUE) and then to fill a telerik:RadComboBox that is situated

inside the panel that is now visible.
If the sql query can't find the value, I do not show the panel and I just show an error message on the page (with a label).

I have tried so many things but I can't understand how to do this.
Thank you for your help.

This is my code in the page with the controls :
(the panel i want to change the property VISIBLE is the one with the ID="PanelMineListe" - the textbox the user uses to write the

first value is the one with the ID="RadTextBoxMine" the he clicks on the imagebutton with te id="BtImgMineValider")

[Solved] cell with a null value returns ' '

When I try to retrive a cell value, its returning ' ' if the value is null. Is something wrong in the code?
why doesn't it just return empty string('') instead of ' '?

Thank you

Change Horizontal SelectedRegion image using Javascript and CSS

Hi,

I would like to change the horizontal selected region image of a slider control on the clientside. I have set to false the EnableEmbeddedSkins property and included a css skin file for the slider control. I see the following class in the css file

.rslHorizontal .rslSelectedregion
{
background:url(../images/Slider/SelectedRegionHorizontalBgr.gif) right top no-repeat;
}
But I want to change the image path on a button click.

Any help is appreciated.

RadAlert for login control

Hi,

I was wondering how I could use the RadWindow in combination with the ASP.NET LoginControl?
I'd like to popup a RadWindow when a user enters the wrong login information, or when an error occurs.

Maybe someone already did this? I'm having trouble to get this working.

Thanks,
Daniel
