Getting the value of other cells in the current row

Hi,

I'm using the loop below to fill a GridDropDownColumn control with items from a customized LINQ query. That part works fine, so I did not include that code.

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If e.Item.IsInEditMode Then

For Each Column As GridColumn In e.Item.OwnerTableView.Columns

If Column.UniqueName = "ProductForReseller" Then

' Code goes here

End If

Next

End If

End Sub

To finalize the query, I need to retrieve a value from one of the other cells (a GridDropDownColumn as well) in the same row. It's probably very simple, but I can't find how to get to that value. The HTML is listed below:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="LinqDataSource1"

AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" GridLines="None"

Skin="Outlook" ShowGroupPanel="True" AllowAutomaticDeletes="True" AllowAutomaticInserts="True"

AllowAutomaticUpdates="True" AutoGenerateColumns="False" Width="62em" Height="37em">

<ClientSettings AllowDragToGroup="True">

<Scrolling AllowScroll="True" />

</ClientSettings>

<MasterTableView DataKeyNames="reseller, product" EditMode="InPlace" CommandItemDisplay="Bottom"

DataSourceID="LinqDataSource1">

<SortExpressions>

<telerik:GridSortExpression FieldName="product" SortOrder="Ascending" />

</SortExpressions>

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldName="reseller" HeaderText="Reseller" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="reseller" HeaderText="Reseller" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<Columns>

<telerik:GridEditCommandColumn EditText="edit" HeaderStyle-Width="7em">

</telerik:GridEditCommandColumn>

<telerik:GridDropDownColumn UniqueName="Reseller" ListTextField="name" ListValueField="id"

DataSourceID="LinqDataSourceReseller" HeaderText="Reseller" DataField="reseller"

DropDownControlType="RadComboBox" AllowSorting="true" HeaderStyle-Width="7em"

AllowFiltering="false">

</telerik:GridDropDownColumn>

<telerik:GridDropDownColumn UniqueName="ProductForReseller" ListTextField="name" ListValueField="id"

DataSourceID="LinqDataSourceProduct" HeaderText="Product" DataField="product"

DropDownControlType="RadComboBox" AllowSorting="true" HeaderStyle-Width="7em"

AllowFiltering="false">

</telerik:GridDropDownColumn>

<telerik:GridDropDownColumn UniqueName="ProductActivationType" ListTextField="name"

ListValueField="id" DataSourceID="LinqDataSource2" HeaderText="Activation type"

DataField="product_activation_type" DropDownControlType="RadComboBox" AllowSorting="true"

HeaderStyle-Width="7em" AllowFiltering="false">

</telerik:GridDropDownColumn>

<telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="Delete"

HeaderStyle-Width="7em">

</telerik:GridButtonColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

I want to retrieve the value of the column "Reseller". How can I do it?

How to rebind a grouping RadGrid without collapsing the items

Hi,

In my current project I have a RadGrid with multilevel grouping of items.

The items displayed on the RadGrid are stored in a DataSet.

When any of items in the DataSet changes (because of some operations on the web page), I redisplay the RadGrid as follows:

this.RadGrid.DataSource = DataSet;
this.RadGrid.DataBind();

However, this causes all the RadGrid items to be collapsed (if any of them has been expanded).

Can you please show me how to redisplay the updated DataSet on the RadGrid and at the same time preserving the expanded items?

Please note that all operations need to be done on the server (instead of client)?

Regards,
Herman

SubObjects (MetaFields + MetaKey) not displayed on client-binding

Hi there,

I really like the telerik ajax tools, but I have a slight problem now: the property value of a subobject is not displayed in the grid: Status.Shortcut. Pasting the json code (extracted by fiddler2) into a json viewser, looks ok.

Telerik-Version: v.2010.2.929.35

Even when creating a client side array, it doesn't display subobject's values.

Alerting the field says: ok - is there.

WHAT CAN I DO? Please help.

Thank you very much.

Client-Side DataBinding:

function UpdateGrid(rows) {

clearError();

var grid = $find("<%=gridTickets.ClientID %>");

var mtv = grid.get_masterTableView();

alert(rows[0].Status.Shortcut); // <--WORKS GREAT!!!!

mtv.set_dataSource(rows);

mtv.dataBind();

return;

}

Page.aspx:

<telerik:RadGrid ID="gridTickets" runat="server" >

<MasterTableView DataKeyNames="Id">

<Columns>

<telerik:GridBoundColumn DataField="Id" HeaderText="Id" Display="false" />

<telerik:GridBoundColumn DataField="Status.Shortcut" HeaderText="Status" />

Hide GridDataItem - Visible False

I have a very simple Grid that includes a hyperlink column using an image as the link:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="sds_Credentials" GridLines="None" Skin="WebBlue" AllowSorting="True" Width="800px">

<MasterTableView AutoGenerateColumns="False" DataKeyNames="IDCredentials" DataSourceID="sds_Credentials">

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

<RowIndicatorColumn>

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

</RowIndicatorColumn>

<ExpandCollapseColumn>

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

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="CredentialName" HeaderText="Credential"

SortExpression="CredentialName" UniqueName="CredentialName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserLogin" HeaderText="Login"

SortExpression="UserLogin" UniqueName="UserLogin">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UserPassword" HeaderText="Password"

SortExpression="UserPassword" UniqueName="UserPassword">

</telerik:GridBoundColumn>

<telerik:GridHyperLinkColumn DataNavigateUrlFields="Website" HeaderText=" "

DataNavigateUrlFormatString="{0}"

UniqueName="Website" AllowFiltering="False" ItemStyle-HorizontalAlign="Center">

<ItemStyle Width="50px" CssClass="radgrid" />

</telerik:GridHyperLinkColumn>

<telerik:GridHyperLinkColumn DataNavigateUrlFields="IDCredentials" HeaderText=" "

DataNavigateUrlFormatString="credentials_details.aspx?IDCredentials={0}"

Text="Details" UniqueName="IDRolodex" AllowFiltering="False" ItemStyle-HorizontalAlign="Center">

<ItemStyle Width="75px" CssClass="tbltdbutton" />

</telerik:GridHyperLinkColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Code behind:

Protected Sub RadGrid1_ItemDataBound1(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

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

Dim hyplnk As HyperLink = DirectCast(item("Website").Controls(0), HyperLink)

hyplnk.ImageUrl = "../../../images/iconIE.gif"

hyplnk.Target = "_blank"

End If

End Sub

This works great.

However, I would like to hide the image if there is no hyperlink in the data field. Something like:

Protected Sub RadGrid1_ItemDataBound1(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

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

Dim value As String = item("Website").Text

If value < "1" Then

Dim hLink As HyperLink = DirectCast(item("Website").Controls(0), HyperLink)

hLink.ImageUrl = "../../../images/iconIE.gif"

hLink.Target = "_blank"

hLink.Visible = False

End If

End Sub

This does not work. Any help would be much appreciated.
