Is there a way to get the headertext to be visible in the header of a GridClientSelectColumn?
I have a customer who insists that "nobody is going to know what it does" if there isn't any text in the header...

How to restore grid filtering settings on page load

I had setup a way to restore the filtering/sorting of the grid through session on page load when it went to "NeedDataSource" function. However, the data I am currently populating has a lot of data, and had to optimize the performance of the grid by starting to use the entitydatasource that you specified in the documentation. The grid is faster, but I am unsure how to restore the filter/sort settings the user made now. Is there another way I can restore?

Filtering on multiple column in dynamic Telerik RAD grid

Dear Friends,

I am preparing dynamic grid using VB.net and RAD grid where columns are getting generated in Run Time. I am trying to apply filter (inbuilt filter) on multiple column at time but application is throwing exception (is neither a DataColumn nor a DataRelation for table Table). This error occurs when I try to apply filter. I am unable to identify root cause. Any input would be appreciated. I am using NeedDataSource() event of Radgrid and this event is throwing above mentioned exception on applying filter.

Thanks in advance.

Simple nested Grid question

I know I have done this before, but I can't remember how....don't you hate being in that situation?!?

I want a simple nested table, of say customers and their orders, displayed in a fashion where customers are the master table, and orders are the detail table. In other words, the grid shows a list of customers and you can expand a customer to see their orders. I can easily get the data in a datatable where the customer data is duplicated on each row which represents a unique order. I want to setup the grid so that I can do one bind and have it all populated. All of the examples now show a separate databind for each of the child(nested) tables. For efficiency and simplicity, I'd like to avoid all of the extra databinds. I know I've done this in the past...

Any help or examples would be greatly appreciated.

Thanks in advance,

ScatterLine enable to move second y axis

I have a chart that has an additional Y Axis which should be on the far right of the chart.

If the chart and series is set as a "Line" I can set the AxisCrossingPoint value for the second Axis and it shows it correctly but if I have the chart type set as "ScatterLine" (which I require) it does not move the Axis and just stays on the left of the chart next to the first Y Axis.

No matter what value I under it does not move at all. I've tried it in code behind and in the HTML. Very strange as it works fine for "Line" type series/chart.

Is this a limitation of ScatterLine?

TreeView set child not to accept children

I have a situation where the data coming in because of the data coming from two separate tables can have the same ID. The ID is mapped to the NodeID (DataFieldID) of the tree view. Because of this I can have two nodes with the same id. Instead of changing my data model converting the ID (int) to a ID (GUID) I would like to see if there is a mechanism in the TreeView where I can check to see if when adding a node check to see if the parent node is accepting a child or not. The below structure represents my tree structure.

When tree evaluates Node 75 with ParentID 37, I want it at the bottom node as it’s a folder vs the first 37 as it not a node that can have children.

NodeID 75

ParentID 37

NodeID 18

ParentID null

NodeID 69

ParentID 18

NodeID 56

ParentID 18

NodeID 37 ß I don’t want it here

Parent 18

NodeID 1

Parent 18

NodeID 12

Parent 18

NodeID 26

Parent 18

NodeID 37 ß I want it here

ParentID 18

Is there an event I can write code for to interrogate the node to see if I can add a child?

Rad Grid column header text not appearing on dynamically generated grid after sort

Hi I dynamically generate the columns in a grid and then load and bind a datasource, everything looks good until I press the column header to sort the grid, the grid does not sort and the column headers disappear. What Am I missing:

The grid declaration:

<telerik:RadGrid

ID="radGridOutput"

runat="server"

AllowPaging="True"

Width="100%"

enableEmbeddedSkins="false"

Skin="CorpsNET"

AllowSorting="true"

pagesize="10"

ClientSettings-AllowKeyboardNavigation="false"

ItemStyle-HorizontalAlign="Center"

HeaderStyle-HorizontalAlign="Center"

AlternatingItemStyle-HorizontalAlign="Center"

onpageindexchanged="radGridOutput_PageIndexChanged"

onsortcommand="radGridOutput_SortCommand"

onitemdatabound="radGridOutput_ItemDataBound">

<PagerStyle Mode="NextPrevAndNumeric" />

<MasterTableView

AutoGenerateColumns="false"

Width="100%"

CommandItemDisplay="None"

PageSize="10">

<Columns>

</Columns>

<EditFormSettings>

<PopUpSettings ScrollBars="None" />

</EditFormSettings>

<NoRecordsTemplate>

<div align="center" style="color:darkorange">---------- No Records to Display -----------</div>

</NoRecordsTemplate>

</MasterTableView

>

<ClientSettings> 
                                </ClientSettings> 
                            </telerik:RadGrid>

Clicking a button loads the grid the first time:

protected void btnCreateReport_Click(object sender, EventArgs e)

{

LoadReport(true);

RadTabStrip1.SelectedIndex = 1;

RadMultiPage1.SelectedIndex = 1;

}

The Code:

protected void LoadReport(bool firstLoad)

{

//if we are paging or sorting don't erase the columns

if (firstLoad == true)

{

radGridOutput.DataSource = null;

radGridOutput.MasterTableView.DataKeyNames = null;

radGridOutput.MasterTableView.Columns.Clear();

radGridOutput.Columns.Clear();

}

if (firstLoad == true)

{

radGridOutput.MasterTableView.AutoGenerateColumns = false;

radGridOutput.AutoGenerateColumns = false;

//string[] _keys3 = { "ID" };

//radGridOutput.MasterTableView.DataKeyNames = _keys3;

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "RosterDate", DataField = "RosterDateString", HeaderText = "Date", SortExpression = "RosterDate" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "RosterDay", DataField = "RosterDay", HeaderText = "Day" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "SponsorNumberAndName", DataField = "SponsorNumberAndName", HeaderText = "Sponsor", SortExpression = "SponsorNumberAndName" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "LocationNumberAndName", DataField = "LocationNumberAndName", HeaderText = "Location", SortExpression = "LocationNumberAndName" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "CrewName", DataField = "CrewName", HeaderText = "Crew", SortExpression = "CrewName" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "SupervisorName", DataField = "SupervisorName", HeaderText = "Supervisor", SortExpression = "SupervisorName" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "NumberOfCrewmembers", DataField = "NumberOfCrewmembers", HeaderText = "# Crew Members", SortExpression = "NumberOfCrewmembers" });

radGridOutput.Columns.Add(new GridBoundColumn() { UniqueName = "TotalHours", DataField = "totalhours", HeaderText = "Total Hours", SortExpression = "totalHours" });

}

if (rdoPayPeriod.Checked == true)

{

PayPeriod _payPeriod = PayPeriodService.GetByID(Int32.Parse(ddlPayPeriod.SelectedValue.ToString()));

radGridOutput.DataSource = RptProjectHoursDetailService.GetReport(_payPeriod.StartDate, _payPeriod.EndDate, ddlSponsor.SelectedIndex>0?Int32.Parse(ddlSponsor.SelectedValue.ToString()):0);

}

else if (rdoSchoolMonth.Checked == true)

{

SchoolMonth _schoolMonth = SchoolMonthService.GetByID(Int32.Parse(ddlSchoolMonth.SelectedValue.ToString()));

radGridOutput.DataSource = RptProjectHoursDetailService.GetReport(_schoolMonth.StartDate, _schoolMonth.EndDate, ddlSponsor.SelectedIndex > 0 ? Int32.Parse(ddlSponsor.SelectedValue.ToString()) : 0);

}

else if (rdoSpecifiedTimePeriod.Checked == true)

{

radGridOutput.DataSource = RptProjectHoursDetailService.GetReport(DateTime.Parse(rdpStartDate.DbSelectedDate.ToString()), DateTime.Parse(rdpEndDate.DbSelectedDate.ToString()), ddlSponsor.SelectedIndex > 0 ? Int32.Parse(ddlSponsor.SelectedValue.ToString()) : 0);

}

radGridOutput.DataBind();

}

The ourput of the GetReport Call is a business object with properties that match the column names and here is the sort command procedure:

protected void radGridOutput_SortCommand(object source, GridSortCommandEventArgs e)

{

LoadReport(false);

}

I can't see anything amiss that would cause this issue. I'm currently not using any type of AJAX management on the page.

Thanks in Advance

Jonathan
