Hi there,

Im currently using RadGrid to display a set of users and Im trying to enable multiple selection of the rows via the GridClientSelectColumn. However, when I turned AllowMultiRowSelection="True" I did not have the ability to select an entire page of rows through the header checkbox. Only once I had enableheadercontextmenus was this made possible. I have noticed that sorting via columns works now also. Why is this the case? Can I get the same effect without context menus? I have attached pictures to better explain what I mean.

Here is the code for my radgrid:

<telerik:RadGrid EnableHeaderContextMenu="true" Skin="Metro" ID="UserListGrid" runat="server" DataSourceID="UserListDatasource" CellSpacing="0" GridLines="None" CssClass="userRadGrid" AllowPaging="True" AllowSorting="True" onpageindexchanged="UserListGrid_PageIndexChanged" AllowMultiRowSelection="True">

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

<MasterTableView DataSourceID="UserListDatasource" AutoGenerateColumns="False">

<CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

<RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column">

<HeaderStyle></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<Columns>

<telerik:GridClientSelectColumn >

</telerik:GridClientSelectColumn>

<telerik:GridBoundColumn DataField="UserId" DataType="System.Guid" FilterControlAltText="Filter UserId column" HeaderText="UserId" SortExpression="UserId" UniqueName="UserId" Visible="False">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserName" FilterControlAltText="Filter UserName column" HeaderText="User Name" ReadOnly="True" SortExpression="UserName" UniqueName="UserName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="FirstName" FilterControlAltText="Filter FirstName column" HeaderText="First Name" SortExpression="FirstName" UniqueName="FirstName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="LastName" FilterControlAltText="Filter LastName column" HeaderText="Last Name" SortExpression="LastName" UniqueName="LastName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Status" FilterControlAltText="Filter Status column" HeaderText="Status" SortExpression="Status" UniqueName="Status">

</telerik:GridBoundColumn>

<telerik:GridButtonColumn ButtonType="LinkButton" UniqueName="DeleteUser">

</telerik:GridButtonColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False" EnableEmbeddedBaseStylesheet="False">

<WebServiceSettings>

<ODataSettings InitialContainerName="">

</ODataSettings>

</WebServiceSettings>

</FilterMenu>

<HeaderContextMenu EnableEmbeddedBaseStylesheet="False" CssClass="GridContextMenu GridContextMenu_Default">

<WebServiceSettings>

<ODataSettings InitialContainerName="">

</ODataSettings>

</WebServiceSettings>

</HeaderContextMenu>

</telerik:RadGrid>

Solution need to refer GAC and not BIN - Telerik.Web.UI

We are migrating SharePoint 2010 solutions to SharePoint 2013. In SharePoint 2013 we need to have dlls only in GAC and not in BIN.

I tried to check if by moving Telerik dlls to GAC the functionality of the site.

1- I moved dlls from BIN to GAC with gacutil.exe.
2- Referred dlls in Visual Studio SharePoint solution from GAC.
3- When i deploy the solution i get the below error.

Could not load file or assembly 'Telerik.Web.UI' or one of its
dependencies. The system cannot find the file specified. Description:
An unhandled exception occurred during the execution of the current web
request. Please review the stack trace for more information about the error and
where it originated in the code.

Exception Details:
System.IO.FileNotFoundException: Could not load file or assembly
'Telerik.Web.UI' or one of its dependencies. The system cannot find the file
specified.
When deploying the SharePoint solution, i can see this in Visual Studio, the warning icon at Telerik.Web.UI.dll (attached image)

What is the way where i can push the Telerik dlls to GAC.

Fetch DatakeyValue of particular row on Radiobbutton click inside RadGrid

Hi
I have a Radiobutton next to every row of RadGrid.
I am trying to access the datakeyvalue of a selected row using radiobutton, i.e., when particular row's Radiobutton of RadGrid is checked, then on 'CheckedChanged' event of RadioButton, I am trying to get the datakey value of that row inside a label or variable.

aspx page Code:

<telerik:RadGrid ID="RadGrid1" EnableViewState="false" runat="server" AllowPaging="true"

AllowSorting="False" AllowFilteringByColumn="true" GridLines="None" OnInit="RadGrid1_Init" OnDeleteCommand="RadGrid1_DeleteCommand">

<ItemStyle Wrap="false"></ItemStyle>

<MasterTableView AllowMultiColumnSorting="true" TableLayout="Fixed" DataKeyNames="Id" ClientDataKeyNames="Id">

<Columns>

<telerik:GridNumericColumn DataField="Id" HeaderText="Id" HeaderStyle-Width="100px" AllowFiltering="False"

FilterControlWidth="50px">

</telerik:GridNumericColumn>

<telerik:GridBoundColumn DataField="Description" HeaderText="Description" AndCurrentFilterFunction="Contains" FilterListOptions="AllowAllFilters">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="" HeaderText="Select">

<ItemTemplate>

<asp:RadioButton ID="rbdSelect" runat="server" AutoPostBack="true" OnCheckedChanged="rbdSelect_CheckedChanged"></asp:RadioButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

.cs page code:

protected void rbdSelect_CheckedChanged(object sender, EventArgs e)

{

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

RadioButton rbd = (RadioButton)item.FindControl("rbdSelect");

if (rbd.Checked==true)

{

string key = item.GetDataKeyValue("Id").ToString();

//string id = RadGrid1.MasterTableView.Items[0].GetDataKeyValue("Id").ToString();

}

Response.Redirect("~/PrintInvoice.aspx");

}

but unable to get the DataKeyValue of selected row.

I also want to call the selected row's DataKeyValue on another page(say Default.aspx), to show the particuar RadGrid row's record on other page(say Default.aspx)

Please help me what is missing in my code?

Change color or overlap one horizontal line

I just completed my first RadHtmlChart (woot!). Everything is just as I wanted it except one thing. This is a column chart showing percentages from 0 to 100. I need the 90% line to either be red, or to somehow overlay a red line along this line to show the target percentage we're shooting for. I'm populating this with SQL, so if it can be done by adding a field to the query that would be fine. Image of what I'm trying to do is attached.

Thanks!!

Load RadLightBox when RadGrid row is selected

Here's what I'm trying to accomplish (and I know it has to be possible, just haven't found a way as of yet). I have a RadGrid which is populated from a database, when a row is clicked I want to open a modal RadLightBox with information pertaining to the selected record (I guess load an ASP.NET page inside the RadLightBox when it loads).

Can anyone help me with this?

neither a datacolumn nor a datarelation for table

Hi,

I have a page with a dropdown and a radgrid with filtering on. Depending on the selection on de dropdown another datatable is loaded in the radgrid.

Problem I have now is when I have a datatable loaded and set a filter on and I change the selection in the dropdown to get another datatable the error 'neither a datacolumn nor a datarelation for table' occurs.

protected void grdEnquiry_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    if (ddlEnquiry.SelectedValue != "-1")
    {
            BLogic.Enquiry Enquiry = new BLogic.Enquiry(Convert.ToInt16(ddlEnquiry.SelectedValue));
           grdEnquiry.DataSource = BLogic.Enquiries.Execute(Enquiry.System, Enquiry.Type, Enquiry.File);
    }
}

protected void ddlEnquiry_SelectedIndexChanged(object sender, EventArgs e)
{
    grdEnquiry.Rebind();
}

How can I fix this?

Kind regards

Suzy

Center nodelines

Hi,

There is a problem with nodelines not centering correctly. Typically when a node has Three Children.
See http://demos.telerik.com/aspnet-ajax/orgchart/examples/drilldown/defaultcs.aspx

As you can see the nodlines are not centered between Hardware and Storage.

How can this be fixed?
