Configure HttpHandlerUrl for RadAsyncUpload

Hi,

I'm trying to configure the HttpHandlerUrl parameter for my RadAsyncUpload object.

I configureIt like this :

myAsyncUploader.HttpHandlerUrl = ("~/loggedin/ImageHandler.ashx?CarId=" + CarId + "&PartnerId=" + PartnerId);

The problem I have always an exception :

 http://vab/loggedin/ImageHandler.ashx?CarId=936&PartnerId=4?type=rau"

...Illegal characters in path
that's because of that "type=rau".



How can I pass my values from server side to that handler ?



How can I configure my RadAsyncUpload to avoid that "type=rau" ?



Thanks,

Hi,

Anyone has an idea if this is a bug or need to set something?

I have a RadListView with RadDataPager.
When I click on the next icon of the pager on the bottom of my page, I want to see the top of the page, I verified the demo at below link from telerik, the demo also shows the same,when you click on the next page icon, the page need to be loaded with data and top of the screen should appear.

http://demos.telerik.com/aspnet-ajax/listview/examples/paging/integratedpaging/defaultcs.aspx

Right Now it loads the data and my screen will be same as before except with new data,as though nothing happened.

Thanks for checking my post, and I appreciate if someone can help me out on this.

'Loads Data into the table

Dim ordlist As New dbrcOrdEst(Session("ConnectionString"))

Dim dt As DataTable = ordlist.ListOrderEstimates(498)

RadGrid1.DataSource = dt

End Sub

However what I want to do is take my textbox column, and return the values back into the database, however I can't get data out of the Textboxes, I know how to manipulate the data once I've got it, but I can't get it. This code does what I want on standard columns but not on textbox columns what am I missing

Protected Sub btnImport_Click(sender As Object, e As System.EventArgs) Handles btnImport.Click

For Each item As GridDataItem In RadGrid1.Items

Dim value As String

value = item.Cells(2).Text

	'DB Functionality

Next

End Sub

Thanks in advance for your help, Ryan

RadGrid using multiple datakeynames - doesnt work

Hi,

I am trying to use the following code to create a hierarchical grid. It works all the way until the grid is expanded to the UserLocationVendorModel GridView (bolded code below). This gridview (table) needs two keys (LocationID and VendorName) passed from the selection on the third level. Could you tell me if I am missing something? I have attached a screenshot of how the grid is not working on the last level.

VB.NET Code:

DefineGridStructure is called in the Page_Load event of the ASP.Net page.

Private Sub DefineGridStructure()

Dim RadGrid4 As RadGrid = New RadGrid

radGrid Popup Form Template Validation Issues

I'm running into a number of issues trying to do validation of controls in a popup form template of a radGrid:

1) None of my client-side validation funtions are firing
2) I cannot get the NEW value of the radEditor in my server-side custom validation function
3) When the insert form is redisplayed with errors, the content of the radEditor displays the original value, not the new value (changes are lost)

I'm using IE 9.0, and radControls Q3 2012.

This is the code for two of my editor controls that are having an issue (and the update button):

<telerik:RadTextBox ID="rtbTItle" runat="server" Width="400" TextMode="SingleLine" Text='<%# DataBinder.Eval(Container, "DataItem.Title") %>' Skin="WebBlue">

</telerik:RadTextBox>

<asp:RequiredFieldValidator ID="rfvTitle" runat="server" ControlToValidate="rtbTitle"

ErrorMessage="You must enter a Title" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">*</asp:RequiredFieldValidator>

<asp:CustomValidator ID="cvTitle" runat="server" ControlToValidate="rtbTitle"

ClientValidationFunction="cvTitle_Validator" OnServerValidate="cvTitle_ServerValidate" EnableClientScript="true"

ErrorMessage="Title cannot contain 'x'" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">x</asp:CustomValidator>

<telerik:RadEditor ID="reItemText" runat="server" BorderStyle="None"

OnClientLoad="reItemText_OnClientLoad" OnClientModeChange="reItemText_OnClientModeChange"

Width="800" Height="300" AutoResizeHeight="false" EnableResize="false" ToolsWidth="800"

ContentAreaMode="Div" Skin="WebBlue" Content='<%# DataBinder.Eval(Container, "DataItem.ItemText") %>'>

</telerik:RadEditor>

<asp:CustomValidator ID="cvItemText" runat="server" ControlToValidate="reItemText"

ClientValidationFunction="cvItemText_Validator" OnServerValidate="cvItemText_ServerValidate" EnableClientScript="true"

ErrorMessage="Item Text is required" ValidateEmptyText="true" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">*</asp:CustomValidator>

<asp:Button ID="btnUpdate" runat="server" ValidationGroup="vgEditor" CausesValidation="true"

Text='<%# IIf(TypeOf Container is GridEditFormInsertItem, "Insert", "Update") %>' CommandName='<%# IIf(TypeOf Container is GridEditFormInsertItem, "PerformInsert", "Update") %>' />

These are my client-side validation functions (neither of which gets fired):

function cvItemText_Validator( sender, args ) {

console.log( "cvItemText_Validator" );

}

function cvTitle_ServerValidate( sender, args ) {

console.log( "cvTitle_ServerValidate" );

}

And these are my server-side validation functions:

Protected Sub cvItemText_ServerValidate(source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs)

System.Diagnostics.Debug.WriteLine("Admin_ManageNews:cvItemText_ServerValidate")

System.Diagnostics.Debug.WriteLine(String.Format(" ItemText: {0}", args.Value))

Dim oItem As GridEditableItem = DirectCast(DirectCast(source, CustomValidator).NamingContainer, GridEditableItem)

Dim oEditor As RadEditor = DirectCast(oItem.FindControl("reItemText"), RadEditor)

System.Diagnostics.Debug.WriteLine(String.Format(" ItemText: {0}", oEditor.Content))

End Sub

Protected Sub cvTitle_ServerValidate(source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs)

System.Diagnostics.Debug.WriteLine("Admin_ManageNews:cvTitle_ServerValidate")

System.Diagnostics.Debug.WriteLine(String.Format(" Title: {0}", args.Value))

Dim oItem As GridEditableItem = DirectCast(DirectCast(source, CustomValidator).NamingContainer, GridEditableItem)

Dim oRTB As RadTextBox = DirectCast(oItem.FindControl("rtbTitle"), RadTextBox)

System.Diagnostics.Debug.WriteLine(String.Format(" Title: {0}", oRTB.Text))

End Sub

Both of the debug statements for the cvTitle validator display the correct value for the Title field, but neither debug statement for the cvItemText validator displays the new values, they display the old value.
