hi,
I just try to setup a basic scenario with RadGrid using CRUD.
So far select and delete works, but update and insert fails. I cannot see, whats going wrong.
Here is my table definition:

CREATE TABLE [dbo].[Projects] (

[ProjectId] INT IDENTITY (1, 1) NOT NULL,

[Project] NVARCHAR (MAX) NOT NULL,

[OrganizationId] UNIQUEIDENTIFIER NOT NULL,

[Created] DATETIME DEFAULT (getdate()) NULL,

[Updated] DATETIME DEFAULT (getdate()) NULL,

PRIMARY KEY CLUSTERED ([ProjectId] ASC)

);

The updated column has a trigger. Hope that is not the problem.
The SqlDataSource is:

<asp:SqlDataSource ID="SqlDataSourceProjects" runat="server"

ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" DeleteCommand="DELETE FROM Projects WHERE (ProjectId = @ProjectId)" InsertCommand="INSERT INTO Projects(Project, OrganizationId) VALUES (@Project, @OrganizationId)" SelectCommand="SELECT Projects.* FROM Projects WHERE (OrganizationId = @OrganizationId)" UpdateCommand="UPDATE Projects SET Project = @Projects WHERE (OrganizationId = @OrganizationId)">

<DeleteParameters>

<asp:Parameter Name="ProjectId" DbType="Int32" />

</DeleteParameters>

<InsertParameters>

<asp:Parameter Name="Project" DbType="String" />

<asp:SessionParameter Name="OrganizationId" SessionField="OrganizationId" DbType="Guid" />

</InsertParameters>

<SelectParameters>

<asp:SessionParameter Name="OrganizationId" SessionField="OrganizationId" />

</SelectParameters>

<UpdateParameters>

<asp:Parameter Name="Projects" DbType="String" />

<asp:SessionParameter Name="OrganizationId" SessionField="OrganizationId" DbType="Guid" />

</UpdateParameters>

</asp:SqlDataSource>

and the radGrid is:

<telerik:RadGrid ID="RadGridProjects" runat="server" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True" CellSpacing="0" Culture="de-DE" DataSourceID="SqlDataSourceProjects" GridLines="None" Skin="Metro">

<MasterTableView DataKeyNames="ProjectId" DataSourceID="SqlDataSourceProjects" CommandItemDisplay="TopAndBottom">

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

<RowIndicatorColumn Visible="True" FilterControlAltText="Filter RowIndicator column">

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

</RowIndicatorColumn>

<ExpandCollapseColumn Visible="True" FilterControlAltText="Filter ExpandColumn column">

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

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="ProjectId" DataType="System.Int32" FilterControlAltText="Filter ProjectId column" HeaderText="ProjectId" ReadOnly="True" SortExpression="ProjectId" UniqueName="ProjectId">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Project" FilterControlAltText="Filter Project column" HeaderText="Project" SortExpression="Project" UniqueName="Project">

</telerik:GridBoundColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False"></FilterMenu>

</telerik:RadGrid>

It would be really nice, if some pros can tell me, what is wrong.
Thanks in advance!

Insert/update grid items in button outside grid

Hi,
I am using the Rad Grid available in "RadControls for ASP.NET AJAX Q3 2012" in Sharepoint 2010(vs2010/c# 3.5).
I have a visual webpart, which has 5 textbox, radgrid and a submit button.

Currently i have the items in the grid getting inserted/deleted/updated in the "oninsertcommand/ondeletecommand/onupdatecommand" events.

However, I want to do these grid changes only when the submit button is clicked. How to achieve this?
Thanks

</div>

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

Hashtable values = new Hashtable();

item.ExtractValues(values);

string ti = values["Title"].ToString();

}

In the Insercommand code, values is coming as null.
How to fix this?
Thanks

CommandItemTemplate and mixed mode

Hi,

in my application, I made a custom Grid control who inherit from RadGrid.

I want every grid to have the ExportToExcel command. But I also want, in some grid, add another "custom" command.

So I create a class who implement the ITemplate interface in my custom grid control, I use this template. It works good.

But now, in some grid, I want to add a custom DropDoxnList in the Grid Command Item Display area. So I add a <CommandItemTemplate> tag in my aspx. But as I can see, this tag is override by my template.

Is it possible to mix programatic and declarative mode ?

Thanks !

Problems Obtaining Date from Java

Hello,

I am simply trying to obtain the date selected from the RadDatePicker control through javascript as I am trying to pass the value to another page as a parameter for an SQL query the page performs when loading. However, I am having a problem with the format the date is returing. I have tried both get_selectedDates and get_textBox with no luck in returning a date that is in a datetime format for the parameter. With get_seletedDates I am getting a long formatted style not in the correct format while get_textBox doesn't return a date value, only that it is an HTMLelement or something along that lines.

Is there a way to get the date that is in the text box portion of the datepicker to return how it actually shows in the date picket, for instance 12/10/2012?

Thanks,
Ron

UpdateCommand and DeleteCommand

Hi,

How to implement the updatecommand and deletecommand code for RAD Grid.? Is there any code samples

I have added the below code in updatecommand:

GridEditableItem editedItem = e.Item as GridEditableItem;

DataTable ordersTable = this.GridData;

//Locate the changed row in the DataSource

DataRow[] changedRows = ordersTable.Select("Title = " + Convert.ToString(editedItem.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Title"]));

In the changedRows line, i am getting error as: Cannot perform '=' operation on System.String and System.Int32.

Thanks
