[Solved] How to set CommandArgument for a dynamically added column in RadGrid

I have a RadGrid which I am binding it to a DataSet in the C# code. I am also adding a column which is a RadButtonColumn dynamically on the Page Load event. My problem is that I cannot able to set the CommandArgument on that column from the values from one of the Columns in the DataSet.
Also using the GoogleLikeFiltering on it which is working fine.

Any help would be appreciated.

Here is my code:
ASCX:

<

radG:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" AllowPaging="True"

AllowSorting="True" AllowFilteringByColumn="True" EnableAJAX="True" EnableAJAXLoadingTemplate="True"

OnNeedDataSource="RadGrid1_NeedDataSource" OnColumnCreating="RadGrid1_ColumnCreating" OnItemCommand="RadGrid1_ItemCommand">

</radG:RadGrid>

C# code:

protected

void RadGrid1_NeedDataSource(object source, Telerik.WebControls.GridNeedDataSourceEventArgs e)

{

ds = GetDataSet();

this.RadGrid1.DataSource = ds;

}

protected void Page_Load(object sender, System.EventArgs e)

{

try

{

if (!IsPostBack)

{

ds = GetDataSet();

this.RadGrid1.MasterTableView.Columns.Clear();

//Add Submit Id button to the Grid

GridButtonColumn gridButtonColumn = new GridButtonColumn();

RadGrid1.MasterTableView.Columns.Add(gridButtonColumn);

RadGrid1.MasterTableView.Columns.Add(

new GridButtonColumn());

gridButtonColumn.UniqueName =

"SubmitId";

gridButtonColumn.DataTextField =

"SubmitId";

gridButtonColumn.HeaderText =

"SubmitId";

gridButtonColumn.DataType =

typeof(int);

gridButtonColumn.SortExpression =

"SubmitId";

gridButtonColumn.ShowSortIcon =

true;

gridButtonColumn.CommandArgument = ds.Tables[0].Columns[

"SubmitId"].ToString();

gridButtonColumn.CommandName =

"processForm";

foreach (DataColumn dataColumn in ds.Tables[0].Columns)

{

RadGrid.

MyCustomFilteringColumnCS gridColumn = new RadGrid.MyCustomFilteringColumnCS();

this.RadGrid1.MasterTableView.Columns.Add(gridColumn);

gridColumn.DataField = dataColumn.ColumnName;

gridColumn.HeaderText = dataColumn.ColumnName;

}

catch (Exception ex)

{

lblMessage.Text =

"PageLoad() " + ex.Message;

}

protected

void RadGrid1_ItemCommand(object source, Telerik.WebControls.GridCommandEventArgs e)

{

try

{

switch (e.CommandName)

{

case "Filter":

{

foreach (GridColumn column in e.Item.OwnerTableView.Columns)

{

column.CurrentFilterValue =

string.Empty;

column.CurrentFilterFunction =

GridKnownFunction.NoFilter;

}

break;

}

case "processForm":

{

// e.CommandArgument returns "SubmitId"
// But does not get the value for SubmitId from the DataSet

break;

}

default:

break;

}

catch (Exception ex)

{

lblMessage.Text =

"RadGrid1_ItemCommand() " + ex.Message;

}

Dynamic control not working properly with radajax manager

Hi

I have created a really basic page with a panel that contains some content and a dynamically created link button. When the link button is clicked the panel is updated. The update is supposed to be done by a partial postback using the radajaxmanager but, for reasons I don't understand, every other time the link button is clicked a full postback is performed rather than a partial postback. In other words i get one partial postback then one full postback and so on.

I have reduced the page to its bare bones below. Please can you tell me how I fix this.

RadMenu from xml and dataset

Hi,
I want to build RadMenu from an xml file and a dataset (xsd).
So I load my xml file into dataset.
Xml file:

    
            <?xml version="1.0" encoding="utf-8"?>  
        
            <MenuConfig xmlns="http://tempuri.org/MenuConfig.xsd">  
        
               <MenuDT> 
        
                <Id>1</Id>      
        
                <Text>House</Text> 
        
                <URL>URL1</URL> 
        
                <CnfgId>1</CnfgId> 
        
                <ParentId>null</ParentId> 
        
              </MenuDT> 
        
              <MenuDT> 
        
                <Id>2</Id>      
        
                <Text>Cars</Text> 
        
                <URL>URL2</URL> 
        
                <CnfgId>1</CnfgId> 
        
                <ParentId>1</ParentId> 
        
              </MenuDT> 
        
            </MenuConfig>

and:

    
            MenuConfig menu = new MenuConfig();//dataset   
 
            menu.ReadXml(MapPath("App_Code/MenuConfig.xml"), System.Data.XmlReadMode.IgnoreSchema);  
        
            RadMenu1.DataSource = menu.Tables["MenuDT"];  
        
            //Establish hierarchy:  
        
            RadMenu1.DataFieldID = "Id";  
        
            RadMenu1.DataFieldParentID = "ParentId";  
        
            //Set Text, Value, and NavigateUrl:  
        
            RadMenu1.DataTextField = "Text";  
        
            RadMenu1.DataValueField = "Id";  
        
            RadMenu1.DataNavigateUrlField = "URL";  
        
            RadMenu1.DataBind();

And I have an error: This constraint cannot be enabled as not all values have corresponding parent values.

I think that ParentId column in xml (set to null) isn't null in c#, it's a normal string.
Is that any solutions to avoid this? At now I change ParentId (in xml) to 0 and set null in c# code (I think that it's not a good idea) :

    
            for (int ii = 0; ii < menu.Tables["MenuDT"].Rows.Count; ii++)  
        
                    {  
        
                        if (Convert.ToInt32((menu.Tables["MenuDT"].Rows[ii]["ParentId"])) == 0)  
        
                        {  
        
                            menu.Tables["MenuDT"].Rows[ii]["ParentId"] = null;  
        
                            menu.Tables["MenuDT"].AcceptChanges();  
        
                        }  
        
                    }

ParentId column in code of xsd file:

    
             <xs:element name="ParentId" msprop:Generator_UserColumnName="ParentId" 

            msprop:nullValue="_null" msprop:Generator_ColumnVarNameInTable="columnParentId" 

            msprop:Generator_ColumnPropNameInTable="ParentIdColumn" 

            msprop:Generator_ColumnPropNameInRow="ParentId" type="xs:string" minOccurs="0" />

Any ideas how to proper make it?
