Export RadGrid (Docx)

Hi,
I’m trying to export a radgrid using this code:

RadGrid1.ExportSettings.Word.Format = Telerik.Web.UI.GridWordExportFormat.Docx;

RadGrid1.ExportSettings.UseItemStyles = true;

RadGrid1.MasterTableView.ExportToWord();

This works but I’m trying to do the following unsuccessfully

1. Make the word file landscape mode
2. Add a header and footer

Please can you clarify how to accomplish these things please?

Add iframe in pageview dynamically

Hi,

I am trying to add tabs, pageviews dynamically, and then iframes in the pageviews. However, on postback, the iframes are not persisted.

HtmlGenericControl iframe = new HtmlGenericControl("iframeA");

PageView pageView = new PageView();

pageView.Controls.Add(iframe);
multiPage.PageViews.Add(pageView);

However, if i statically do it (as below), the iframes are persisted. Can you please show me a way to make this work.

Thanks,
Raj

Export to Excel - Boolean challenge

Hi,

I need to place an "X" in all cells that have a true value in the export. I've seen similar posts, but I am using Format="Xlsx" and trying to accomplish this task using the OnInfrastructureExporting event handler as follows:

protected void grdUserAdmin_InfrastructureExporting(object sender, GridInfrastructureExportingEventArgs e)

{

var colCount = e.ExportStructure.Tables[0].Columns.Count;

var rowCount = e.ExportStructure.Tables[0].Rows.Count;

ExportStyle headerStyle = new ExportStyle();

headerStyle.ForeColor = Color.White;

headerStyle.BackColor = Color.Blue;

headerStyle.Font.Bold = true;

// Set the header style for all columns

for (var i = 1; i <= colCount; i++)

{

e.ExportStructure.Tables[0].Cells[i, 1].Style = headerStyle;

e.ExportStructure.Tables[0].Columns[i].Width = 200; // Would like auto-width !!

}

// Place an "X" in cells assigned to a boolean data field if value is true

var headerText = "";

for (var c = 1; c <= colCount; c++)

{

for (var r = 1; r <= rowCount; r++)

{

if (r == 1)

{

headerText = e.ExportStructure.Tables[0].Cells[c, r].Value.ToString();

continue;

}

if (headerText == "Active")

{

var x = e.ExportStructure.Tables[0].Cells[c, r].Value.ToString();

System.Diagnostics.Debug.WriteLine("Cell Value: " + x);

if (Convert.ToBoolean(e.ExportStructure.Tables[0].Cells[c, r].Value.ToString()))

e.ExportStructure.Tables[0].Cells[c, r].Value = "X";

}

The value for the variable x above is always "" or null (hard to tell in the Output section of VS).
I know that my data for column Active should have all true values.
The conversion to boolean fails!
I think I'm close.
What am I doing wrong?
Thanks in advance for any advice.
Jim

How to set focus to RadTextBox in RadGrid EditForm

I have a RadGrid that uses an EditForm template in order to lay the controls out according to the wishes of the customer. I have not been able to get the RadTextBox within the template to receive focus when it goes into edit mode.

<telerik:RadGrid ID="rgComments" runat="server" AutoGenerateColumns="False" Width="100%" AllowSorting="True" CellSpacing="0" GridLines="None" Height="455px">

<MasterTableView CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add Comment" CommandItemSettings-ShowRefreshButton="true" TableLayout="Fixed" EditMode="EditForms" DataKeyNames="iNoteID,qwImageID">

<EditFormSettings EditFormType="Template">

<FormTemplate>

<div style="position: relative; height: 215px; width: 800px;">

<telerik:RadTextBox ID="rtbComment" runat="server" Width="795px" Height="165px" ClientEvents-OnLoad="taComment_onload" />

<asp:ImageButton ID="ibSave" runat="server" ImageUrl="~/Images/Save.png"

CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>' style="position: absolute; left: 10px; top: 180px;" />

<asp:ImageButton ID="ibCancel" runat="server" ImageUrl="~/Images/Cancel.png" CommandName="Cancel" style="position: absolute; left: 70px; top: 180px;" />

</div>

</FormTemplate>

</EditFormSettings>

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderStyle-Width="30px" ItemStyle-HorizontalAlign="Center" EditImageUrl="~/Images/Edit.png" UniqueName="gecEdit" />

<telerik:GridBoundColumn DataField="dtCreateDate" HeaderText="Create Date" HeaderStyle-Width="66" HeaderStyle-HorizontalAlign="Center" DataFormatString="{0:MM/dd/yyyy HH:mm}" ReadOnly="True" UniqueName="gbc_dtCreateDate" />

<telerik:GridBoundColumn DataField="cLoginName" HeaderText="Create By" HeaderStyle-Width="66" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" ReadOnly="True" UniqueName="gbc_cLoginName" />

<telerik:GridBoundColumn DataField="cNote" HeaderText="Comment" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="500px" MaxLength="1024" UniqueName="gbc_cNote" />

<telerik:GridButtonColumn ButtonType="ImageButton" CommandName="Delete" HeaderStyle-Width="30px" ItemStyle-HorizontalAlign="Center" ImageUrl="~/Images/Delete.png" UniqueName="bcDelete" />

</Columns>

</MasterTableView>

<ClientSettings><Scrolling AllowScroll="true" /></ClientSettings>

</telerik:RadGrid>

When the form goes into edit mode I want to put the current Comment text into the RadTextBox and set focus there. I am using this code to try and do that.

void rgComments_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.IsInEditMode && e.Item is GridEditableItem)

{

GridEditableItem item = e.Item as GridEditableItem;

RadTextBox radTextBox = ((RadTextBox)(((GridEditFormItem)(item)).FindControl("rtbComment")));

// It works if I comment out this line, but then control is not populated with the necessary text

radTextBox.Text = ((DataRowView)(((GridItem)(item)).DataItem)).Row["cNote"].ToString();

radTextBox.Focus();

}

I have tried adding a client-side onload event handler for the control to set the focus. It gets called but still won't put focus into the control.

Can you help me figure this out?

How to restore grid filtering settings on page load

I had setup a way to restore the filtering/sorting of the grid through session on page load when it went to "NeedDataSource" function. However, the data I am currently populating has a lot of data, and had to optimize the performance of the grid by starting to use the entitydatasource that you specified in the documentation. The grid is faster, but I am unsure how to restore the filter/sort settings the user made now. Is there another way I can restore?

Filtering on multiple column in dynamic Telerik RAD grid

Dear Friends,

I am preparing dynamic grid using VB.net and RAD grid where columns are getting generated in Run Time. I am trying to apply filter (inbuilt filter) on multiple column at time but application is throwing exception (is neither a DataColumn nor a DataRelation for table Table). This error occurs when I try to apply filter. I am unable to identify root cause. Any input would be appreciated. I am using NeedDataSource() event of Radgrid and this event is throwing above mentioned exception on applying filter.

Thanks in advance.

Simple nested Grid question

I know I have done this before, but I can't remember how....don't you hate being in that situation?!?

I want a simple nested table, of say customers and their orders, displayed in a fashion where customers are the master table, and orders are the detail table. In other words, the grid shows a list of customers and you can expand a customer to see their orders. I can easily get the data in a datatable where the customer data is duplicated on each row which represents a unique order. I want to setup the grid so that I can do one bind and have it all populated. All of the examples now show a separate databind for each of the child(nested) tables. For efficiency and simplicity, I'd like to avoid all of the extra databinds. I know I've done this in the past...

Any help or examples would be greatly appreciated.

Thanks in advance,

Grid
