Javascript in gridview

Hi All,
I am working on this task for past 2 days and could not solve this problem. I have a radgrid with a column of linkbutons inside it. when a user clicks on any link button, I pop up a javascript message based on some conditions.

ScriptManager.RegisterStartupScript(Page, this.GetType(), "message", string.Format("confirm_select('{0}','{1}');", RadGrid_IDPicker.ClientID,row.RowIndex + 1), true);

inside the function confirm_select, I have to make one row bold, the row that user clicked on and make the previous bolded row as normal/unbolded.
To achieve this, I am looping though the radgrid and unbolding all the rows and bolding the currenlty selected row if the user presses ok, but if the user pressed cancel, I would leave the previous row as bolded. below is my code

<script type="text/javascript">

var selectedRowIndex = -1;

function confirm_select(gridViewID, rowIndex) {

debugger;

var gridview = document.getElementById(gridViewID);

var master = gridViewID.get_masterTableView();

if (confirm("You are leaving the parent level of the currently selected ID, are you sure?") == true) {

for (var i = 1; i < gridview.rows.length; i++) {

//not the selected row

if (i != rowIndex)

gridview.rows[i].style.fontWeight = 'normal';

//selected row

else {

gridview.rows[i].style.fontWeight = 'bold';

selectedRowIndex = rowIndex;

}

else {

if (selectedRowIndex != -1)

gridview.rows[selectedRowIndex].style.fontWeight = 'bold';

}

</script>

I am getting an error right here

var master = gridViewID.get_masterTableView();

I would not have done the get get_masterTableView(), but I could not loop thorugh the gridview rows to make them bolded or unbolded. Below is the code for my gridview.
I also tried

var master = gridview.get_masterTableView();

but above line of code didn't work either.

<telerik:RadGrid ID="RadGrid_IDPicker" AllowSorting="True" PageSize="100" AllowPaging="True"

runat="server" GridLines="None" OnPageIndexChanged="RadGrid_IDPicker_PageIndexChanged"

OnPageSizeChanged="RadGrid_IDPicker_PageSizeChanged" Width="1500px" Visible="false" OnItemDataBound="RadGrid_IDPicker_DataBound" >

<MasterTableView RetrieveAllDataFields="true" AutoGenerateColumns="false" DataKeyNames="ID" >

<Columns>

<telerik:GridTemplateColumn UniqueName="TemplateLinkColumn" AllowFiltering="false" HeaderText="ID">

<ItemTemplate>

<asp:LinkButton ID="ID_Link" runat="server" OnClick="MCLID_Link_Click" Text='<%#Bind("ID") %>' CommandName="Bold"></asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="TAG">

<ItemTemplate>

<asp:Label ID="lbltag" runat="server" Text='<%#Bind("TAG") %>'></asp:Label>

</ItemTemplate>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

I don't have anything else defined. this gridview is inside the radPanelbar so the whole gridview is enclosed in this

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" Width="1500px" BackColor="#E6E6E6" ExpandMode="MultipleExpandedItems">

<Items>

<telerik:RadPanelItem runat="server" Text="ID Picker" Expanded="true" >

<Items>

<telerik:RadPanelItem Text="" Expanded="true">

<ItemTemplate>

//radgrid is right here

i am not sure what am I doing wrong, but I spend lot of hours on it and this is not working.

Any help will be highly appreciated.

Conditional RadGrid update

Hi,

I have relatively simple scenerio where I have to check some conditions before updating data. To manage data I'm using RadGrid with autoupdate. I would like to check some conditions before update (i.e. if the name already exists, if an issue date is greater then other max issue date in database etc.). What is the best practice to make such check and how to stop update if some conditions are not met?
I thought about SqlDataSource updating event but I don't know how to read values from controls in edit form of RadGrid. Maybe other event is much more efficient in this case. I appreciate your support in this case as well as snippet of example code is welcome.

Best Regards,

Darek

Not answered how can i attach a RadFilter to a RadGrid which is located in a user control

i have a RadGrid in a usercontrol.
i have an aspx page that contains the usercontrol and a RadFilter.
how can i assign the FilterContainerID of the RadFilter to the RadGrid?

i already tried to directly giving it the ID as such:

<telerik:RadFilter

ID="rfCustomFilter" runat="server"FilterContainerID="RadGrid1"/>

and i have also tried to assign filterContainerID in code behind as such:
rfCustomFilter.FilterContainerID = "RadGrid1";

both did not work, and i get an error when Adding an expression:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

At which event, the CommandItem (export to excel button) is created and added to the MasterTableView?

At RadGrid.ItemCreated() event, that button is already created.

At which event, the CommandItem (export to excel button) is created and added to the MasterTableView?

I'd need to add a custom button to the CommandItem.

Thanks,

Need help converting Table to RadGrid (with sortable columns)

I have the following table

<table>

<tr>

<td>First Row, Cell 1</td>

<td>First Row, Cell 2</td>

</tr>

<tr>

<td colspan="2">Second Row, Cell 1</td>

</tr>

</table>

Can some suggest a RadGrid equivalent that allows me to keep the second row but the cells in the first row become GridBoundColumns? I think it has to be GridBoundColumn, because this allows sorting by column.

Drop Down Value Retrieval Error

I've got another RadGrid problem. One column in my grid is a DropDown that is getting its values from a SqlDataSource. The cell is defined as:

<telerik:GridDropDownColumn DataField="store" HeaderText="Store" UniqueName="store" DataSourceID="SqlDataSource2"

ListTextField="store" ListValueField="store">

</telerik:GridDropDownColumn>

The drop down list is getting populated fine. I am using edit in place for the editing and can select a value from the list okay. On the back end for the update, I've got (in part):

protected void RadGrid1_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

string store = (editedItem["store"].Controls[0] as DropDownList).SelectedValue.ToString();

}

I'm getting an error at run time after editing a row when I include that code. If I remove the code that adds the store drop down from the update, it works fine (but of course doesn't update that field.) I've tried other variations such as "string store = (editedItem["store"].Controls[0] as DropDownList).SelectedItem.Value" with no luck.

The error is "Message: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
Line: 6
Char: 62099
Code: 0"

Any ideas? Thanks!
