No alt text for binary image column

If a field used to display the image alt text is NOT type of string (e.g. int) then the alt text is not generated
E.g.

<telerik:GridBinaryImageColumn

DataField="MyImage"

DataAlternateTextField="MyId" DataType="System.Int32"

DataAlternateTextFormatString="{0}"

ImageAlign="Middle"

HeaderText="Image" FooterText="Image"

HeaderStyle-Width="50"

AllowFiltering="false" AllowSorting="false"

Groupable="False" ResizeMode="Fit" ImageHeight="50px" ImageWidth="50px"

ReadOnly="True" DefaultImageUrl="../img/noimage.png">

</telerik:GridBinaryImageColumn>

Cannot remove pager from RadGrid

Hello again,
This time I've encountered a problem with RadGrid.

I have following grid:

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadGrid ID="UserGrid" runat="server" Culture="pl-PL" AutoGenerateColumns="False" PageSize="100"

CellSpacing="0" GridLines="None" OnNeedDataSource="UserGrid_NeedDataSource"

AllowCustomPaging="True"

AllowFilteringByColumn="True" AllowSorting="True" EnableLinqExpressions="False"

EnableHeaderContextMenu="True" OnInsertCommand="UserGrid_InsertCommand" OnUpdateCommand="UserGrid_UpdateCommand"

OnItemDataBound="RadGrid1_ItemDataBound" GroupingEnabled="False">

<mastertableview allowcustompaging="true" allowpaging="true" datakeynames="Id"

pagerstyle-alwaysvisible="true" EditMode="InPlace" CommandItemDisplay="Top" >

<Columns>

<telerik:GridEditCommandColumn UniqueName="EditCommandColumn" ButtonType="ImageButton"

HeaderStyle-Width="56px" Resizable="false">

<HeaderStyle Width="56px"></HeaderStyle>

<ItemStyle CssClass="MyImageButton" />

</telerik:GridEditCommandColumn>

<telerik:GridBoundColumn HeaderText="lblName"

UniqueName="Name" DataField="Name" >

</telerik:GridBoundColumn>

<telerik:GridDropDownColumn HeaderText="lblType" ColumnEditorID="GridDropDownColumnEditor1">

</telerik:GridDropDownColumn>

</Columns>

</mastertableview>

</telerik:RadGrid>

<telerik:GridDropDownListColumnEditor ID="GridDropDownColumnEditor1" runat="server" />

</ContentTemplate>

</asp:UpdatePanel>

I'd like to hide/remove pager, so I try to remove pagerstyle-alwaysvisible property or to set it to false, the grid is rendered correctly and the pager is not shown. But whenever I try to edit a row, a javascript error is shown:

Sys.ArgumentUndefinedException: Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: type

{name: "element", mayBeNull: true, domElement: true, optional: true}

As a result, DropDownList is disabled (I cannot open the list).

What can be the reason of this strange behaviour? In other pages I just removed all the properties associated with pager/paging and it works fine, but I didn't use GridDropDownListColumnEditor there, so no errors occured.

My web application is being developed using .NET 3.5 and Sharepoint 2010.

Thank you in advance,
Paweł

Edit: I've just noticed that removing allowcustompaging="true" allowpaging="true" properties causes the same problem.

Wrapping the code block within RadCodeBlock does not resolve the error

Hi,

As soon as I drag a RadGrid onto my page, when loading the page I get the following error:

Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.

Exception details:

Error Message	Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.
Error Source	Telerik.Web.UI
Stack Trace	at Telerik.Web.SkinRegistrar.RegisterCssReference(Page _page, Control _control, String _url) at Telerik.Web.SkinRegistrar.RegisterCssReferences(ISkinnableControl _control) at Telerik.Web.UI.RadCompositeDataBoundControl.RegisterCssReferences() at Telerik.Web.UI.RadCompositeDataBoundControl.OnPreRender(EventArgs e) at Telerik.Web.UI.RadGrid.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Target Site	Void RegisterCssReference(System.Web.UI.Page, System.Web.UI.Control, System.String)

Wrapping the RadGrid into a radCodeBlock doesn't solve the problem. Only removing the RadGrid from the page gets everything back to normal.
Any idea?

Thanks,
John

Radgrid e.Canceled = true; Not working

Decided to make a new thread per http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-footer-validation.aspx

Using the ItemDataBound, everything is working except the e.Canceled = true; line. When the values don't match I get the response.write "Cancelled" message on my page as intended but the e.Canceled = true; line doesnt execute and the updates execute . And when they do match, update executes sucessfully and I dont get the message as intended.

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridFooterItem)

{

GridFooterItem fitem = (e.Item as GridFooterItem);

string value1 = fitem["CALENDAR_DAYS_MTD"].Text;

string value2 = fitem["WEEKENDS_MTD"].Text;

string value3 = fitem["HOLIDAYS_MTD"].Text;

string value4 = fitem["BUSINESS_DAYS_MTD"].Text;

int footervalue1;

int footervalue2;

int footervalue3;

int footervalue4;

int.TryParse(value1, out footervalue1);

int.TryParse(value2, out footervalue2);

int.TryParse(value3, out footervalue3);

int.TryParse(value4, out footervalue4);

//to get the value only.

if (footervalue2 + footervalue3 + footervalue4 != footervalue1)

{

e.Canceled = true; // Cancel Update

Response.Write("Cancelled");

}

Appending rows to Telerik Rad Grid

Hi,

How do I programmatically append new records to the rad grid without using add new record option of rad grid?

I have to perform new record insertion when user clicks on a button outside grid.

Is this feature supported in rad grid?

Thanks,
Jay
