Filtering problem at openaccesslinqdatasource with my treeview's Checkedvalues(multiple selection).

Hi. first i am sorry because of the this long message.
there is a treeview, button and listview. when i hit button listview's datasource should be filtered with treeview checked values.

treeviewKat
(
CheckBoxes=true,
CheckChildNodes=true,
TriStateCheckBoxes=true
)
and I am filtering an OpenAccessLinqDataSource with this treeviewKat's checked values.

How can i filter to OpenAccessLinqDataSource with treeviewKat's CheckedValues (multiple values).

I tried to add every node.value in the nodecollections of checked nodes to linqdatasource. but i cant get result.

Taking node.value of treeview is correct. i can see true added OADLSSoruTV.whereparameters, but i cant see listview update (lvSoruTV).

code-behind below:

protected void RadButton2_Click(object sender, EventArgs e)

{

OADLSSoruTV.WhereParameters.Clear();

IList<RadTreeNode

> nodeCollection = 

                  treeviewKat.CheckedNodes;

foreach (RadTreeNode node in nodeCollection)

{

OADLSSoruTV.Where = 

                        "KategoriId ==Int32?(@KategoriId)";

OADLSSoruTV.WhereParameters.Add ( "KategoriId",TypeCode.Int32,

node.Value.ToString() );

}

OADLSSoruTV.DataBind();

}

Adding parameter OADSSoruTV is correct because i tried same thing with dropdownlist instead of treeview and it is working good.

Rowindex resets at each page

A page requires that the value of RowIndex continue to increase when I go to the next page, yet it resets to 0 in the first column of each page.

I want the index to be 0, 1 , 2 , 3 on the first page, then 4, 5, 6, 7 on the next page; however, on the next page it would go to 0, 1, 2, 3 instead of continually increasing. Does anyone have any idea why this would be happening?

Here are the attributes of the grid:
<telerik:RadGrid ID="_EmpGrid" Skin="Web20" GridLines="None" runat="server" PageSize="10"
AllowPaging="True" OnItemCreated="_EmpGrid_ItemCreated">

This is the Javascript behind the grid
function ShowEditPanel(id, title_id, rowIndex)
{
var grid = $find("<%= _EmpGrid.ClientID %>");

var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();
grid.get_masterTableView().selectItem(rowControl, true);

window.radopen("EmpPanel.aspx?EmpId=" + id + "&TitleId=" + title_id + "&Key=" + rowIndex, "EmpDialog");
return false;
}

and this is the function the grid calls upon

protected void _EmpGrid_ItemCreated(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)
{
HyperLink editLink = (HyperLink)e.Item.FindControl("_EditLink");
editLink.Attributes["href"] = "#";
editLink.Attributes["onclick"] = String.Format("return ShowEditPanel('{0}', '{1}', '{2}');", e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Employee_ID"], e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Employee_title_Id"], e.Item.ItemIndex);
}
}

The issue is that If user go to Edit mode in the Grid and then user puts some values in text boxes at the time user clicks the Enter button in Chrome browser, the application will take the another button control and make the changes as per the button event, So i need to disable the Enter Key in chrome browser, But its working fine in firefox browser.
The issues in in chrome browser only, I have attached my grid and script code snippet below.

Can anyone help me regarding this issue..

This is my script..

function OnEnterKeyPress(sender, args) {

var keypressed = args._keyCode;

if (keypressed == "13") {

document.getElementById('<%=lblMsg.ClientID %>').innerHTML = "Please use the Update Button";

args.set_cancel(true);

}

This is my Grid..

// This is my grid //

<telerik:RadGrid ID="RGRateCorrection" runat="server" AutoGenerateColumns="false"

Skin="Vista" OnNeedDataSource="RGRateCorrection_NeedDataSource" OnUpdateCommand="RGRateCorrection_UpdateCommand"

Width="1000px" Height="300px" HeaderStyle-Width="500px" ItemStyle-Width="500px"

Rebind() not calling _NeedDataSource

I have a grid that's using the following settings:

<telerik:RadGrid ID="RadGridTest"

runat="server"

AllowPaging="True"

AllowCustomPaging="True"

GridLines="None"

OnNeedDataSource="RadGridTest_NeedDataSource"

PageSize="25"

OnItemDataBound="RadGridTest_ItemDataBound"

AutoGenerateColumns="false"

EnableHeaderContextMenu="true"

EnableLinqExpressions="false"

EnableHeaderContextFilterMenu="true"

AllowSorting="True"

MasterTableView-AllowCustomSorting="true"

OnSortCommand="RadGridTest_SortCommand"

MasterTableView-AllowMultiColumnSorting="true"

AllowFilteringByColumn="true">

<PagerStyle Mode="NextPrevAndNumeric/>

<HeaderContextMenu OnItemClick="HeaderContextMenu_ItemClick">

</HeaderContextMenu>

<ClientSettings AllowColumnHide="True">

<ClientEvents OnGridCreated="GetGridObject"></ClientEvents>

</ClientSettings>

</telerik:RadGrid>

When sorting using the header context menu, unlike just clicking on the header, no SortCommand event is fired. I found a thread where you recommended using the ItemClick event on the header.

The problem is that this event is called after the grid rebinds once you click it, and even if you explicitely call RadGridTest.Rebind() in the event it doesn't take it. The only solution I've found so far is to set the datasource to null and then call rebind.

// Doesn't change the grid at all

protected void HeaderContextMenu_ItemClick(object sender, RadMenuEventArgs e)

{

if (e.Item.Text == "Clear Sorting")

{

string columnName = e.Item.Attributes["ColumnName"]; // ["columnUniqueName"] Returns Null!?

// Prepare conditions for sorted data

RadGridTest.Rebind(); // Never actually raises NeedDataSource

}

// Updates the grid with the correct changes.

protected void HeaderContextMenu_ItemClick(object sender, RadMenuEventArgs e)

{

if (e.Item.Text == "Clear Sorting")

{

string columnName = e.Item.Attributes["ColumnName"]; // ["columnUniqueName"] Returns Null!?

// Prepare conditions for sorted data

RadGridTest.DataSource = null;

RadGridTest.Rebind();

}

Is setting the datasource to null the correct approach, or is there something I am missing.

LinkButton in RadGrid GridTableCell with Static ID does not fire ItemCommand Event

I have a LinkButton control that I am adding to a GridTableCell, but when I assign it an ID, the Item Command Event does not fire.

	    ///WORKS

	    LinkButton linkButton = new LinkButton();
            linkButton.Text = name;
            linkButton.CommandArgument = locationString;
            //linkButton.ClientIDMode = System.Web.UI.ClientIDMode.Static;
            //linkButton.ID = string.Concat("LinkButton_", Guid.NewGuid().ToString("N"));
            //linkButton.CommandName = string.Concat("LocationNameLink_", linkButton.ID);            
            linkButton.CommandName = "LocationNameLink";   
  
            return linkButton;
	    ///DOES NOT WORK
	    LinkButton linkButton = new LinkButton();
            linkButton.Text = name;
            linkButton.CommandArgument = locationString;
            linkButton.ClientIDMode = System.Web.UI.ClientIDMode.Static;
            linkButton.ID = string.Concat("LinkButton_", Guid.NewGuid().ToString("N"));
            linkButton.CommandName = string.Concat("LocationNameLink_", linkButton.ID);
	   return linkButton;

Thoughts?

DetailItemTemplate not collapsing

I have a grid with a DetailItemTemplate defined.

On the PreRender method of the grid, I get all the GridGroupHeaderItems and I set the Expanded property to false.

The grid displays correctly except the DetailItemTemplate rows are visible.

When I open it using the control, it shows the rows and associated detail rows, and when I collapse it on the page it works correctly -- just not from the PreRender method.

Is there something else that I need to set or a workaround?

Thanks,
Todd.

TargetFolder problem

Hi, I set up the vb.net demo as per below
http://demos.telerik.com/aspnet-ajax/imageeditor/examples/imageupload/defaultvb.aspx?product=asyncupload#qsf-demo-source

When I add a "TargetFolder" the temp file creates itself in RadUploadTemp, but immediately disappears.

It only works if I remove the target folder. i.e the temporary file remains in RadUploadTemp and I can manipulate the image.

Why is it failing if I set a TargetFolder?

<telerik:RadAsyncUpload ID="AsyncUpload1" runat="server" OnClientFilesUploaded="OnClientFilesUploaded"

OnFileUploaded="AsyncUpload1_FileUploaded" MaxFileSize="2097152" AllowedFileExtensions="jpg,png,gif,bmp"

AutoAddFileInputs="false" Localization-Select="Select" TargetFolder="~/images">
