Color DropDownList inside RadGrid EditItemTemplate Mode

Hello,

I have a RadGrid with a DropDownList in its edititem Template area.

I would like to color the items depending on Org Name.

Here is the RadGrid definition (I just removed columns before and after for ease of reading)

<telerik:RadGrid ID="RadExamGrid" runat="server" AutoGenerateColumns="False"

AllowSorting="True" ExportCellFormating="RadExamGrid_ExportCellFormatting"

GridLines="Both" EnableViewState="True"

MasterTableView-AllowSorting="True" PagerStyle-AlwaysVisible="True"

PagerStyle-Position="TopAndBottom" ResolvedRenderMode="Classic"

OnNeedDataSource="RadExamGrid_NeedDataSource" Skin="Sunset" >

<ExportSettings ExportOnlyData="True" FileName="Allocation"

HideStructureColumns="True" OpenInNewWindow="True" Excel-FileExtension="xls" Excel-Format="Biff" SuppressColumnDataFormatStrings="True">

<Excel Format="Biff" />

</ExportSettings>

<MasterTableView AllowPaging="True" PageSize="10" CommandItemDisplay="Top" Caption="Exams Received"

InsertItemPageIndexAction="ShowItemOnCurrentPage" DataKeyNames="EntryNum" OverrideDataSourceControlSorting="True" CommandItemSettings-ShowExportToExcelButton="True" CommandItemSettings-ShowExportToPdfButton="False" CommandItemSettings-ShowExportToWordButton="True" >

<Columns>

<% COLUMNS before not included %>

<%--Org No Column --%>

<telerik:GridTemplateColumn HeaderText="Org Name" SortExpression="OrgName" HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="250px">

<ItemTemplate>

<%# DataBinder.Eval(Container.DataItem, "OrgName")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadDropDownList ID="RadddlOrg" runat="server" AutoPostBack="True" Width="300px" DataTextField="OrgName" DataValueField="OrgNo"

SelectedValue='<%# DataBinder.Eval(Container.DataItem, "OrgNo")%> ' OnSelectedIndexChanged="RadddlOrg_SelectedIndexChanged" CausesValidation="false">

</telerik:RadDropDownList>

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Field is required" ControlToValidate="RadddlOrg" Display="Static" Font-Bold="True" SetFocusOnError="True" ForeColor="#FF0000"></asp:RequiredFieldValidator>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<% COLUMNS after not included %>

</Columns>

<EditFormSettings EditColumn-ButtonType="PushButton">

<EditColumn FilterControlAltText="Filter EditCommandColumn1 column"

UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<PagerStyle Position="TopAndBottom" />

</telerik:RadGrid>

Here is my RadGrid Item DataBound method.

Protected Sub RadExamGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadExamGrid.ItemDataBound

Dim cmdItem As GridCommandItem = DirectCast(RadExamGrid.MasterTableView.GetItems(GridItemType.CommandItem)(0), GridCommandItem)

Dim intResult As Integer = 0

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim btnDelete As ImageButton = DirectCast(item("ReceivedCommand").Controls(0), ImageButton)

Dim itemValue As String = item.DataItem("RCVDTS")

If itemValue.Trim = "" Then

btnDelete.Visible = True

Else

btnDelete.Visible = False

End If

''want dropdownlist for edit;

If TypeOf e.Item Is GridEditableItem And e.Item.IsInEditMode Then

Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

Dim drpOrg As Telerik.Web.UI.RadDropDownList = DirectCast(editItem.FindControl("RadddlOrg"), Telerik.Web.UI.RadDropDownList)

Dim txtStudno As Telerik.Web.UI.RadTextBox = DirectCast(editItem.FindControl("RadtxtStudNo"), Telerik.Web.UI.RadTextBox)

For i = 0 To objEXR.OrgNameDataView.Count - 1

Dim li As New DropDownListItem

li.Value = objEXR.OrgNameDataView.Item(i).Item(0)

li.Text = objEXR.OrgNameDataView.Item(i).Item(1)

If li.Text.Trim = "4HR CHALLENGER EXAM SESSION" Then

li.ForeColor = System.Drawing.Color.Blue

End If

drpOrg.Items.Add(li)

Next

If txtStudno.Text.Trim = "" Then

txtStudno.Text = "1"

End If

End Sub

I read some articles on RadDropDownList.VisualListItemFormatting Event, but was unsuccessful to implement it. I went with simple approach to create list item, and then set its forecolor. Thanks in advance for any help.

Save Multiple Grids in Batch Edit Mode and Data From Other Controls with one Button Click

Hello,

I have two grids with EditMode="Batch". Both grids subscribe to the OnBatchEditCommand event for saving data. I am trying to save data from both of these grids, as well as data from other controls on the page with one button click.

I have tried suggestions from http://www.telerik.com/forums/save-radgrid-in-batcheditmode-from-external-button and http://www.telerik.com/forums/how-do-i-save-2-radgrids-by-only-1-outside-button but can't seem to achieve the desired functionality... Is this possible?

Thank you in advance.

Looking for the right way to configure datasource...

I'm trying to find the best way to configure my radgrid to accomplish this scenario.

Here is the scenario:

(This all occurs within my Default.aspx page)

1. A radtextbox control prompts the user to input the customer number. The customer number is validated using data coming from a table adapter.

2. I want to pass the customer number entered above into another query (table adapter) and return a item details dataset using it. This is the dataset

that I want my RadGrid connected to.

-------------------

I have been able to figure out how to accomplish everything above by using the RadGrid (onneeddatasource) event.

Here is where my problem comes in:

---------------------

3. One of the columns in my item details dataset (column name PRINT) is a Boolean datatype. I have set the PRINT column in my datatable associated with the table adapter to read-only = false. I need to give the user ability to (check or un-check) that column in my RadGrid and have it update the datatable only. I have no requirement to go back and update the SQL database with the updated datatable. This data is going to be used to generate a sql report which is included in this project.

In summary, I haven't been able to find a way to query and store results in a local datatable and allow the radgrid to update that local datatable. I've looked at the batch editing capability, but I don't like the way it requires having to press the save button in between paging. I'd like to code it so that the user can click the check box and it immediately saves the result to the data table.

Is there anyone out there that can give me some advice or an example of how I can accomplish this problem?

Scheduler Timeline with multiple days in horizontal time slots

Hi all,

I would like to show events for more than one day in timeline view with horizontal time slots.
I found a solution to show multiple days in timeline view from the following link:
http://www.telerik.com/support/code-library/view-with-custom-date-range-and-swipe-support

But, time slots are showing in vertically. I want to show horizontally.
Time slots for two days are showing in my scheduler timeline, but events are not showing.
Telerik is not supporting this feature or any way to do it.

I attached image of my scheduler timeline with two days.

Thanks,
Lin

Add custom filter option under Default filter, but expression will not combine to other filter's expression

Hi,

I am trying to add a custom filter option under default filter, in my grid there are two columns will use default filter, and others will be under FilterTemplate

1. newly added custom filter option called "Large Losses" will be added to both of columns filter. I donot want. (I used js to invisible the one).

2. my Large Losses custom option is working with expression. but the issue is that after my Large Losses option is applied to the grid, I apply another filter option to the grid from another column, the Large Losses filter is gone, only the one applied after it shown in the grid. The other way around, If I apply other filter option first, then apply my Large Losses on top of it, it works fine, both filter result under AND shown in the grid.

3. Please help, while I debugging the code, found that my Large Losses expression is not kept when I apply another filter on top of it.

aspx:

<telerik:GridNumericColumn UniqueName="totalincurred" HeaderText="Incurred" DataField="totalincurred" Aggregate="Sum"
AllowFiltering="true" DataType="System.Decimal" FilterControlWidth="80px" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right" FooterStyle-HorizontalAlign="Right" DataFormatString="{0:N}">
</telerik:GridNumericColumn>

C#:

protected void LossesGrid_Init(object sender, EventArgs e)
{
GridFilterMenu filterMenu = LossesGrid.FilterMenu;
RadMenuItem menuItem = new RadMenuItem();
menuItem.Text = "Large Losses";
menuItem.Value = "LargeLosses";
LossesGrid.FilterMenu.Items.Add(menuItem);

filterMenu.ItemClick += new RadMenuEventHandler(filterMenu_ItemClick);

}

protected void filterMenu_ItemClick(object sender, RadMenuEventArgs e)
{
GridFilteringItem filterItem = LossesGrid.MasterTableView.GetItems(GridItemType.FilteringItem)[0] as GridFilteringItem;
filterItem.FireCommandEvent("Filter", new Pair(e.Item.Value, e.Item.Attributes["totalincurred"]));
}

protected void LossesGrid_ItemCommand(object sender, GridCommandEventArgs e)
{

if (e.CommandName == RadGrid.FilterCommandName)
{
AOId = (this.Master as Main).AccountOverviewId;
VersionNo = (this.Master as Main).VersionNumber();

Pair filterPair = (Pair)e.CommandArgument;

if (filterPair.First.ToString() == "LargeLosses")
{
e.Canceled = true;
string newFilter = "(totalincurred >= 25000)";

if (LossesGrid.MasterTableView.FilterExpression == "")
{
LossesGrid.MasterTableView.FilterExpression = newFilter;
}
else
{
LossesGrid.MasterTableView.FilterExpression = "((" + LossesGrid.MasterTableView.FilterExpression + ") AND (" + newFilter + "))";
}

LossesGrid.Rebind();
}
}

}

The only things I can I can think of is permissions or IIS settings
