I have a situation where the RadGrid Filter criteria is saved, but, the RadGrid doesn't execute the Filter expression (yes, I tried ReBind()) upon re-loading Persistence.  Also, Sorts are not re-loaded either.  Only the Filter criteria value is re-loaded upon returning to the page.

 

I have a RadTabStrip with (3) RadGrids.  I implemented RadPersistenceManager with PersistenceSettings for each RadGrid, loading and saving with Page_Load and Page_Unload (code below, if needed).  Everything was working great; Sort & Filter were the same when I returned from exiting the app or returning from another page.  Something changed, though.  I'm not sure where.  The RadGrid Filter criteria is saved, but, the RadGrid doesn't execute the Filter expression, and the Sorts don't re-load.  What could've possibly happened to cause this?

 

 

 <telerik:RadPersistenceManager ID="RadPersistenceManager_AssetTabs" runat="server">
    <PersistenceSettings>
        <telerik:PersistenceSetting ControlID="RadGrid1" />
        <telerik:PersistenceSetting ControlID="RadGrid2" />
        <telerik:PersistenceSetting ControlID="RadGrid3" />
    </PersistenceSettings>
</telerik:RadPersistenceManager>

 

protected void Page_Load(object sender, EventArgs e)

{
    string theKey = "TelerikAspNetRadControlsPersistedState";
    theKey = "StorageProvider_" + Session["UserName"].ToString();
    RadPersistenceManager_AssetTabs.StorageProviderKey = theKey;
    var fileNameAndPath = Server.MapPath("~/App_Data/" + theKey);

    //bool IsPersistenceLoaded = (bool)Session["PersistenceLoaded"];
    if (File.Exists(fileNameAndPath)) // && !IsPersistenceLoaded)
    {
        try
        {
            if (!IsPostBack)
            {
                RadPersistenceManager_AssetTabs.LoadState();
            }
        }
        catch (Exception theError)
        {
            Console.WriteLine("Exception for RadPersistenceManager LoadState: {0}", theError);
        }
    }
}

protected void Page_Unload(object sender, System.EventArgs e)
{
    try
    {
        RadPersistenceManager_AssetTabs.SaveState();
    }
    catch (Exception theError)
    {
        Console.WriteLine("Exception for RadPersistenceManager SaveState: {0}", theError);
    }
}

Hello Team,

Am using PivotGrid control for displaying pivot data.

but the issue is, when I open pivot in IE browser in that case empty line is being added whereas this issue does not occur in case of Chrome browser. Kindly refer screenshot attached.

Let me know how can this be fixed in IE browser.

Export to excel works fine, except the column headers have "Sorted ascSorted desc" appended to every column header name in the excel file.  Does anyone have any suggestions or seen this before?

Thanks

Good afternoon,

My RadGrid does not need horizontal scroll until it goes into in-place edit mode - then there are text boxes to the right of the box containing the grid, but no scroll bar.

Any suggestions?

<telerik:RadGrid ID="RadGrid1" GridLines="None" runat="server"   AutoGenerateColumns="false"  OnNeedDataSource="RadGrid1_NeedDataSource" OnItemDataBound="RadGrid1_ItemDataBound"
                 OnUpdateCommand="RadGrid1_UpdateCommand" OnInsertCommand="RadGrid1_InsertCommand" AllowSorting="True" AllowMultiRowSelection="True" ClientSettings-Scrolling-AllowScroll="true">
        <ClientSettings  >
            
            <Selecting AllowRowSelect="true" /></ClientSettings>
        <MasterTableView AutoGenerateColumns="False" DataKeyNames="HorseKey"  ClientDataKeyNames="HorseKey" EditMode="InPlace" 
             CommandItemDisplay="Top"  >

Hey, 

So I downloaded the telerik toolkit trial first and then I downloaded visual studio 2017. I followed the link below to add the toolkit into visual studio, but I'm getting a message that says "There are no usuable controls in this group. Drag an item onto this text to add it to the toolbox." Is there another method to try for adding the toolkit?

I'm assuming the update is the root cause of this issue. This code worked previously and now causes an error "You need to have a DynamicManager control on the page and register your data control with it in order to use a DynamicControlParameter". The RadListView is not compatible with a DynamicManager control.

 

The code causing this error:

 
    Private Sub rbtnAddLocation_Click(sender As Object, e As EventArgs) Handles rbtnAddLocation.Click
        rlvLocations.InsertItemPosition = RadListViewInsertItemPosition.FirstItem
        rlvLocations.ShowInsertItem()
        rbtnAddLocation.CommandArgument = rdlMembers.SelectedValue
        rbtnAddLocation.Enabled = False
    End Sub

 

The offending lines are the two with rlvLocations.

Updates are really getting frustrating to new Telerik user here.

Hi,

I am witnessing some strange behaviour in my HtmlChart.

When displaying unstacked data everything looks fine (first attched file).

 

But when turning staking on, for some reason some of the columns parts look 1000 times bigger than they should (second attached file).

The data is strictly the same in these 2 examples, the only difference is turning line.Stacked true or false, nowhere in the code do we multiply any value by 1000.

Telerik Web UI is version 2017.1.118.45.

The same page works perfectly with Telerik Web UI 2014.1.403.40.

Is it a known issue? Is there any known solution?

Here is the ascx code:

<radS:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="1000px" Height="500px">
        <PlotArea>
            <XAxis DataLabelsField="day">
                <TitleAppearance Text="Days" Visible="true"></TitleAppearance>
                <LabelsAppearance DataFormatString="{0}"/>
                <MinorGridLines Visible="false"></MinorGridLines>
                <MajorGridLines Visible="false"></MajorGridLines>
            </XAxis>
            <YAxis>
                <TitleAppearance Text="Count" Visible="true"></TitleAppearance>
                <LabelsAppearance DataFormatString="{0}"></LabelsAppearance>
                <MinorGridLines Visible="false"></MinorGridLines>
            </YAxis>
        </PlotArea>
        <Legend>
            <Appearance Visible="true"></Appearance>
        </Legend>
    </radS:RadHtmlChart>

 

The binding part in the C#:

RadHtmlChart1.PlotArea.Series.Clear();
 
for(int i=1; i<dtTemp.Columns.Count;i++)
{
    Telerik.Web.UI.ColumnSeries line = new Telerik.Web.UI.ColumnSeries();
    line.Name = string.Format("{0} ({1})",Names[i],Totals[i]);
    line.Stacked = true;
    //line.Stacked = false;
    line.LabelsAppearance.Visible = false;
    line.LabelsAppearance.DataFormatString = "{0}";
    line.DataFieldX = "day";
    line.DataFieldY = dtTemp.Columns[i].ColumnName;
    RadHtmlChart1.PlotArea.Series.Add(line);
}
 
RadHtmlChart1.DataSource = dtTemp;
RadHtmlChart1.DataBind();

 

Thank you.

I've got a theme set for my entire project in the App_Themes folder. Within this folder I have a style sheet which, among other things, specifies the style for all radGrids.  I now have a requirement to completely change the style on one particular grid within one user control.  There are other grids in this user control that shouldn't change.

What's the best way to override the style on one grid on one user control?

Thanks.

I apologize if this has been answered elsewhere.  I have what, I think, is a simple problem.  I am trying to access one of the controls in the LayoutTemplate of a RadListView via javascript.   Here is the ListView code:
<telerik:RadListView ID="rlvApproval" runat="server">
    <LayoutTemplate>
        <table>
            <tr>
                <td style="width: 250px;">
                </td>
                <td style="width: 200px; font-weight: bold;">
                </td>
            </tr>
        </table>
        <asp:PlaceHolder ID="itemplaceholder" runat="server" />
        <table>
                                <tr>
                <td style="width: 250px;">
                    <asp:Label ID="lblName" runat="server" Text="Total" Font-Bold="true" />
                </td>
                <td style="width: 200px; font-weight: bold;">
                    <telerik:RadNumericTextBox ID="txtTotalValue" runat="server" ReadOnly="true" DataType="System.Decimal"
                        Skin="Web20">
                        <NumberFormat DecimalDigits="0" />
                    </telerik:RadNumericTextBox>
                </td>
            </tr>
              
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <table>
            <tr>
                <td style="width: 250px;">
                    <asp:Label ID="lblName" runat="server" Text='<%# Eval("name") %>' />
                </td>
                <td style="width: 250px;">
                                                <telerik:RadNumericTextBox ID="txtValue" runat="server" DataType="System.Decimal"
                        Skin="Web20" DbValue='<%# DataBinder.Eval(Container.DataItem, "value") %>' MaxValue="100"
                        MinValue="0" AutoPostBack="false" >
                        <NumberFormat DecimalDigits="0" />
                        <ClientEvents OnValueChanged="ValidateWeighting" />
                    </telerik:RadNumericTextBox>
                </td>
            </tr>
        </table>
    </ItemTemplate>
    <EmptyDataTemplate>
        <div class="message">
            <asp:Label ID="lblEmptyMessage" runat="server" SkinID="messageBig" Text="Error loading approval information..." />
        </div>
    </EmptyDataTemplate>
</telerik:RadListView>
Whenever the txtValue is updated, I fire a javascript function to determine if the values are 100% based on the current total value that is set in the codebehind.  Here is the code I have that is working:
function ValidateWeighting(sender, eventArgs) {
    var object = document.getElementById('ctl00_ContentPlaceHolder1_Weighting1_rlvApproval_txtTotalValue_text');
    var object2 = document.getElementById('<%= rlvApproval.ClientID %>');
    var current = eval(object.value);
    var old = eventArgs.get_oldValue();
    var newval = eventArgs.get_newValue();
    var tmp = current + (newval - old);
    if (tmp == 100) {
        document.getElementById('<%= btnSave.ClientID %>').disabled = false;
    }
    else {
        document.getElementById('<%= btnSave.ClientID %>').disabled = true;
    }
    object.value = tmp;
}
However, The id to get the object for the txtTotalValue control was obtained through "View Source".  What I am looking for is the right way to do this that avoids browser differences, web server differences, etc.
Any thoughts?
