Dropdown list selected value to display existing data stored

<

telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateEditColumn="True" CellSpacing="0" DataSourceID="objGetHaulsByTripcode" GridLines="Horizontal" AutoGenerateColumns="False">

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

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

<telerik:GridDropDownColumn DataField="TechniqueName" DataSourceID="getTechniques"

HeaderText="Technique" ListTextField="TechniqueFullName"

ListValueField="TechniqueCode" UniqueName="TechniqueName"

ColumnEditorID="TechniqueName" Reorderable="False"

Resizable="False"></telerik:GridDropDownColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:SqlDataSource ID="objGetHaulsByTripcode" runat="server" ConnectionString="<%$ ConnectionStrings:FisheriesConnectionString %>"

SelectCommand="SELECT [TripCode], [VessReg], [TechniqueName] FROM [vwDisHaulsDetailsAll] WHERE ([TripCode] = @TripCode) ORDER BY [TripCode], [VessReg]">

<asp:ControlParameter ControlID="ddlTripCode" Name="TripCode" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:SqlDataSource>

<asp:SqlDataSource ID="getTechniques" runat="server" ConnectionString="<%$ ConnectionStrings:FisheriesConnectionString %>"

ProviderName="System.Data.SqlClient" SelectCommand="SELECT DisTechnique.Code AS [TechniqueCode], DisTechnique.Name AS [TechniqueFullName] FROM DisTechnique INNER JOIN DisGearTechniqueAllowed ON DisTechnique.Code = DisGearTechniqueAllowed.Code INNER JOIN DisTrips ON DisGearTechniqueAllowed.METHOD_CODE = DisTrips.GearCode WHERE ([TripCode] = @TripCode)">

<asp:ControlParameter ControlID="ddlTripCode" Name="TripCode" PropertyName="SelectedValue" Type="String" />

</SelectParameters>

</asp:SqlDataSource>

Hi,

For my GridDropDownColumn DataField="TechniqueName" how can I show the [TechniqueName] FROM [vwDisHaulsDetailsAll] WHERE ([TripCode] = @TripCode) in the grid?

In select mode, the dropdown does not show anything in the row(s). I wish it to show what it stored in the database table, based on a TripCode.

Now, in Edit mode, it lists the 4 options ok. But I wish the selected value to be what has been already stored in the database for a row, based on a Trip Code.

Any advice please? Hope this question makes sense!

Thanks, Ida

disable button on client file select

I want to disable another button on my page when the user chooses a file for upload. It looks like this has to be client side, which is fine, but when I wire up the OnClientAdding function it gets called when the page loads, and the ClientID of the RadUpload control evaluates to null.

How can I achieve what I want?

Thanks.

Export 1 NestedViewTemplate to Html

I have RadGrid with a quit extended NestedView where I show the details if the Item in a Html table. The Html is styled and there is photos in the table.

Now I would like to export only this NestedViewTemplate from this one Grid Item when the user click on a button inside the NestedViewTemplate.

Is this possible?

I have tried modify this sample:

http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-export-to-excel-biff-format-hierarchy-and-selected-items.aspx#2816333

By adding a NestedViewTemplate an expand those in the Prerender event. But first of I can't it to print the NestedViewTemplate and the export contains the headers.

Could some one point me in the right direction? Thanks :-)

bool isExport = false;

protected void Button1_Click(object sender, EventArgs e)

{

Session["SelectedItems"] = RadGrid1.SelectedItems;

isExport = true;

RadGrid1.ExportSettings.IgnorePaging = true;

RadGrid1.ExportSettings.UseItemStyles = true;

RadGrid1.ExportSettings.ExportOnlyData = true;

RadGrid1.MasterTableView.ExportToExcel();

}

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

if (isExport)

{

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

item.Expanded = true;

}

Default Item

Is there a quick an easy way to make sure that first item is selected? After data-binding, the control doesn't have a selection (and the default message would show if set). I was looking for a property to make sure the first item is selected instead of no selection. I can easily set it in code-behind, but thought I might be missing something.

Thanks,
Chris

work out the position of the Token being removed

I would like to know if its possible to work out which item, by its initial Position, is being removed.
My preference is to do this in the Code Behind, but the only Event that is vaguely right is the autoCompleteRecipients_EntryRemoved event, but i believe this event fires too late for what i need.

in Javascript, the event seems to be OnClientEntryRemoving.

basically, when the Token is clicked to be removed - lets say its the 5th Token out of 10 - i want to store the fact that it is the 5th Token.
I will then use this number else-where in my code.

EDIT: it is possible for my AutoCompleteBox to have two different Tokens (entities) with the same text although they are not the same entity from the database.
e.g: my AutoCompleteBox would have a Token called 'David' which refers to the 'Manager' Entity, and another Token called 'David' which refers to the 'Director' Entity, so i cant find the position simply by the Text showing on the Token.

thanks for any help you can give.

How to set selected tag from code-behind

Using the TagCloud control, how can I set the selected Tag from the server-side code? I need the TagCloud control pre-select one of the items when the control is loaded. For example if the items = tag1, tag2, tag3, I want to set the initial selection to tag2 in the Page_Load event. How can I achieve this? Thanks!
