I'm having a problem with my RadAjaxPanel and my viewstate.

We are keeping our last ten viewstates in session. The problem is on a certain page.. the user hits the page and selects a CATEGORY from a drop down. Another drop down is populated with CategoryTYPES depending on the CATEGORY that was selected.

To keep the page from posting back, I have a RadAjax panel around the controls on the page.

After selecting a CATEGORY/TYPE, the user can add that combination to a listbox and select another CATEGORY/TYPE. These selections are then used in a search that populates a RadGrid.

Our legacy system allowed the users to then use the browser back / forward buttons to move backward and forward, which loaded each viewstate version from memory. So each step was saved.

With my RadAjax panel on the page though, the hidden __VIEWSTATE value is not being updated on the page. I can see my SavePageStateToPersistenceMedium Sub is firing and that my subsequent viewstates are being saved to memory, but since the hidden field isn't being updated on the page, I'm continually loading the wrong version of the page (the original version from when I first hit the page)  after doing an actual postback.

I think my main problem is the hidden field __VIEWSTATE is not getting updated. The hidden field has no runat="server" on it since it's being put there dynamically, and although I've managed to find the control and read the value from it, I can't find a way to update it during the ajax postback.  

I've tried adding EnableViewState="true" to my ajax panel, but I'm still not updating the hidden field on the page when then ajax postback occurs.

I know I can't be the only one who's run into this and I'm hoping someone has a solution or even a work around that will allow me to keep track of where I'm at and what viewstate version I'm supposed to be loading when the user tries to browse backwards or forwards.

And yes, I know.. but they insist on being able to use the BACK and FORWARD browser buttons, so I have to live with it.  :)

I appreciate any suggestions or tips on how I can get around this problem...

Hi,

If i create a control like this:

RadDatePicker date = new RadDatePicker();
            date.EnableTyping = false;
            date.ShowPopupOnFocus = true;

Disabling typing also disables Popup.. ..but i only want the popup, that's why i disable typing! :D

So now i have a control that allows no input at all!

Disabling typing should actually force popup = true

Also, you should probably not show a caret in the input box when typing is disabled. Very misleading.

basically I have radtabstripe with 3 levels so for 1st and 2nd i want default behavior of radtab but for third level i want to show tab items in dropdown / radcombo format. so is there any way to style 3rd level different than 1 and 2nd so that i get 3 level dispalyed in combobox style. or is there any way i can have radcombo box for 3rd level.

Hi Mike,

As you suggested i have started a new thread here. Could you please let me know by what time this will be functioning properly?

Hi,

I create a Grid on server-side on button click event.
The grid has been created fine, but the mfunctionality of the grid doesn't work.

For example, I am trying to change page size, but the event isn't fired.
Here is my code:

 

 

 

protected void btnGenerate_Click(object sender, EventArgs e)

{

PopulateGrid();

}

protected void PopulateGrid()

{

GridPlaceHolder.Controls.Clear();

RadGrid GridReport = new RadGrid();

GridReport.GroupingSettings.CaseSensitive =

false;

GridReport.ID =

"GridReport";

GridReport.Skin =

"Gray";

GridReport.EnableViewState =

false;

GridReport.ClientSettings.EnableRowHoverStyle =

true;

GridReport.ClientSettings.ClientEvents.OnRowSelected =

LoadReport(GridReport);

GridPlaceHolder.Controls.Add(GridReport);

}

private void LoadReport(RadGrid GridReport)

{

 

 

    string reportName = "Report_Operations";

    switch (reportName )

     {

    case "Report_Operations":

     GridReport.MasterTableView.DataKeyNames =

    new string[] { "OperationID" };

     GridReport = BLL.BO.Reports.

    Operations.GenerateReportColumns(ref GridReport);

    break;
}

 

 

 

private void GridReport_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{
    //do something

    GridReport.DataSource = dt;}

 

 

void GridReport_PageIndexChanged(object source, GridPageChangedEventArgs e)

 {

            // DO SOMETHING, HERE THE BREAKPOINT NEVER HITS!
}

Thanks for your help!

In option Telerik.Charting.Styles.DefaultFigures ... there are some figures. Not all satisfy me. There are inserting new pictures? If yes, how I do it?

How do I access a GridTemplateColumn in the Grid row that was clicked?

With the getDataKeyValue() method I can get the value of GridBoundColumns after defining the columns using the ClientDataKeyNames property of the MasterTableView.

But how can I get the value of GridTemplateColumns?

Hi

As I can add css to my page with EnableEmbeddedBaseStylesheet and EnableEmbeddedSkins disabled. 
i did this in my page have this:
<telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server">
     <StyleSheets>
     <telerik:StyleSheetReference  Path="../Vista/FormDecorator.Vista.css"/>
     <telerik:StyleSheetReference Path="../Vista/ToolTip.Vista.css" />
     </StyleSheets>
  </telerik:RadStyleSheetManager>

and my web.config have this:

<add key="Telerik.Web.UI.StyleSheetFolders" value="~/Vista"/>
<add key="Telerik.EnableEmbeddedSkins" value="false" />
<add key="Telerik.EnableEmbeddedBaseStylesheet" value="false" />

and nothing that could be happening or that I need to add
thank you very much beforehand 

Hi there.

Could someone please give me a pointer as to how to display the column filters only if the number of rows INITIALLY returned by a grid is greater than x?

I say "initially" for a reason. Let's say x above is 20. If the grid initially returns 30 rows the filters will appear. But if I filter the grid so that only  5 rows come back based on my filter expression then the grid needs to know this is 5 out of 30 rows so it still needs to show the filters. I.e. It's the 30 that is important here, not the 5.

I'm assuming I will use the onDataBound event. But I dont know how to get the number of rows returned. And I assume there is a "total" variable I can tap into that is the number of rows regardless of any filter applied?

Thanks in advance.

Hello,
    I am attempting to implement batch updating using controls that are located within the EditItemTemplate of a GridTemplate Column.  I am currently using a OnPreRender event to set all datagrid columns to edit mode.  The idea is the user should then be able to select values in a radcombobox and check box located in a GridTemplate column for each entry in the grid.  After the users has made their edits to multiple rows in the grid they should be able to hit a single button to process all updates.  I am attempting to use an approach similar to what is described in this article however I have been having difficulties with my OnItemCommand event as I have been unable to retrieve the values the radcombo box and check box in my EditItemTemplate have been set to.  
    Below is what I am attempting to do currently.  Also I would like to remove the "update" and "cancel" links from the EditItemTemplate rather then set the text of the link to nothing in a OnItemCreated event as I am doing currently.  Thanks in advance for helping out a Telerik beginner.
