how can I export all the pages in a RadGrid but not only the populated page into Excel? ( I dont use Telerik export method)

Hello,

I use a third party tool (NPOI) with RadGrid to export both rows and charts (images) into Excel. When user clicks to a button it exports the populated data in RadGrid1 which is only Page1. I need to export all the pages in this RadGrid, not only the page RadGrid has been populated. (I can direct connect datatable to NPOI but in this case RadGrid1 related functions like Filtering, Sorting won't work so this is not a solution)

So, how can I export all the pages in a RadGrid but not only the populated page into Excel? I don't use Telerik export method...Any Ideas?

Thank you,
Ervin

Paging and ViewState issue

Hello,

I have a RadGrid that I'm binding dynamically with different data table based on the choice customer makes but when I "enable" the ViewStateMode of the RadGrid to maintain the filter value, paging messes up.

If I am on page 3 of RadGrid with DataTable "A" then when the datasource of RadGrid is changed to Data Table "B" it shows page 3 instead of page 1. Also, the forward buttons of the pager changes the page but numeric button 2 stays highlighted even if I have clicked 7 times..

Please help!

Best Regards,
Effat

Can't get loading panel to show

Hi,

I have some RadGrids on a page, and I'd like a loading panel to show up during AJAX calls. For example, let's focus on a virtual scrolling grid.

On this demo page, we can see virtual scrolling, and a loading panel showing up as you scroll. For some reason, no matter what I try, I can't get the loading panel to show. The AJAX magic does work, though.

Are there common pitfalls that I should be aware of, or something?

My code:
In a first control:

<telerik:RadScriptManager ID="scriptManager" runat="server" />

(...)

<telerik:RadAjaxManager ID="ajaxManager" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="resultGrid">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="resultGrid" LoadingPanelID="resultAjaxPanel"/>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

In a sub control:

<telerik:RadAjaxLoadingPanel ID="resultAjaxPanel" runat="server" />

<telerik:RadGrid ID="resultGrid" runat="server" AutoGenerateColumns="False" ShowHeader="False"

AllowPaging="True" PageSize="30" PagerStyle-Visible="false" CellSpacing="0" GridLines="None" OnItemCreated="resultGrid_ItemCreated" OnItemCommand="resultGrid_ItemCommand" OnItemDataBound="resultGrid_ItemDataBound">

<MasterTableView>

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

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

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

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

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

</ExpandCollapseColumn>

<Columns>

<telerik:GridMaskedColumn UniqueName="idColumn" FilterControlAltText="Filter idColumn column" DataField="Id" Visible="false">

</telerik:GridMaskedColumn>

<telerik:GridBoundColumn DataField="Extension" FilterControlAltText="Filter extensionColumn column" UniqueName="extensionColumn">

<ItemStyle Width="20px" CssClass="extensionColumn" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Title" FilterControlAltText="Filter linkColumn column" UniqueName="linkColumn">

<ItemStyle CssClass="titleColumn" />

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn>

<ItemTemplate>

<a

href='<%# this.ResolveUrl("Preview.ashx?" + Insite.Web.Widgets.FilterSearch.Preview.IdParam + "=" + Eval("Id")) %>' target='_blank'><

asp:Image ImageUrl="~/Widgets/FilterSearch/images/icon_loupe.png" runat="server" /></a>

</ItemTemplate>

<ItemStyle HorizontalAlign="Right" Width="16px" />

</telerik:GridTemplateColumn>

<telerik:GridButtonColumn ButtonType="LinkButton" CommandName="Add"

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

GridButton get clicked row value from client scipt

Hi,

I have a grid control to which I add a GridButtonColumn. Later, I add an OnClick client event. This part works fine. The image is displayed within each row of the grid and if I click on the image, the javascript function is executed.

Now from within the javascript function, I want to access a value from the grid. The value should come from the row which contains the button which was clicked on. Looking on the internet, I have managed to find out how to get this to work if a row has been selected. The problem is that when you click on a grid button, the row containing the grid button is not necessarily selected e.g. If I first select a row and then click on the button, I can get the value, but if I just click on one of the buttons without first selecting a row, I am aunable to determine the row containing the button. The clicked button itself is inside a specific row so there must be some way to get it.

Below are a few snippets of relevent code. Any help would be greatly appreciated.

Creating the button:



var inchisIncomingEmail = new GridButtonColumn();

grid.MasterTableView.Columns.Add(inchisIncomingEmail);

Adding the onclick event to the button

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

ImageButton btnColumn1 = (ImageButton)item["objhisIncomingEmailID"].Controls[0];

btnColumn1.Attributes.Add("OnClick", "IncomingEmailClick()");

}

client side javascript event handler. Only works as expected if a row is selected prior to clicking on the button - even though the button itself is inside a specific row.

function IncomingEmailClick(obj, args) {

IncomingEmailOpenWindow('<%=ResolveUrl("~/Modules/Common/HistoryDetail.aspx") %>', obj, null);

}

function IncomingEmailOpenWindow(url, grid, closeFn) {

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

var items = gridc.get_masterTableView().get_selectedItems();

if (items.length > 0) {

url = url + '?id=' + items[0].getDataKeyValue('objhisID') + '&type=<%=(int)ListType %>' + '&objId=<%=ItemGuid %>';

}

var win = radopen(url, null);

win.set_modal(true);

win.setActive(true);

if (closeFn != null) {

win.OpenerWindowCloseFn = closeFn;

}

Dynamic group

hi

based on the example you have http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourceheadertemplates/defaultvb.aspx
where your 4 speakers has static settings in the resource style and mapping.

I am having an eviromment where my speakers are very dynamic. we engage many different speakers on an assignment basis and we insert speaker as we engage them and delete them when don't require their speaking engagement.

Grouping is done vertically and we uses Timeline to display speakers on the left without displaying time.

How do i go about it doing dynamically?

Thanks

Determine Column ID of Filtered Column

Hello,

I'm using filtering on my grid. When the user selects a filter the "Item_Command" event is triggered where I can retrieve the Filter pair from the command argument. From this argument I can get the "filterPair.first", "filterPair.second", ..etc. Using this approach I can get access to the column name that the user is filtering, but I need the associated Column ID. Is it possible to associate more data with this filter or command argument? Maybe I could add an attribute to the filter Textbox when the filter is created, then read it on ItemCommand?

Please let me know if you have suggestions on the best approach.

protected void grdSummary_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.FilterCommandName)

{

Pair filterPair = (Pair)e.CommandArgument;

string strOperator = filterPair.First; // Starts With, ..etc

string strColumn = filterPair.Second; // Column Filtering On

string searchValue = ((TextBox)(e.Item as GridFilteringItem)[filterPair.Second.ToString()].Controls[0]).Text;

           string columnId = ??
