gridclientselectcolumn clearing when opening an edit form

I have a radgrid which uses form templates for updating records in the grid. I also need to use this form to update multiple rows in the grid at the same time (global updates). I have a gridclientselect column and the code behind inplace to successfully do the update for multiple selected rows. I am running into one small problem which I need help. The checkboxes clear upon opening the edit form. The correct information is saved in RadGrid1.SelectedItems, but I am failing to understand why the checks are removed from the gridclientselectcolumn field. Is there a way to keep the items selected until the form is closed?

Please let me know if you need code snippets to help answer this question.

Thanks a bunch!

RadComboBox with CheckBoxes inside a DataGrid

I'm attempting to have the new RadComboBox with checkboxes="true" bound to a SqlDataSource inside a radGrid.

It works fine when just 1 item is selected, but when I select multiple Items it doesn't work. I try to convert all the selected countries ids into a comma separated string and then add an updateparameter to update the database. But it doesn't update it. I'm not sure what I'm doing wrong.

I'll also like to know the proper way to populate the checkboxes in the radcombobox automatically, when editmode is enabled on the grid.

<telerik:GridTemplateColumn HeaderText="Select Countries" ItemStyle-Width="240px" UniqueName="List_of_Countries" >

<ItemTemplate>

<%# DataBinder.Eval(Container.DataItem, "List_of_Countries")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox runat="server" ID="rdComboCountries" DataTextField=

"country_name"

CheckBoxes="true" Width="250px" DataValueField="country_id" DataSourceID="SqlDataSourceCountries"
SelectedValue='<%#Bind("List_of_Countries") %>'>

</telerik:RadComboBox>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<asp:SqlDataSource runat="server" ID="SqlDataSourceCountries" ConnectionString="<%$ ConnectionStrings:mydbConnectionString %>"

ProviderName="<%$ ConnectionStrings:mydbConnectionString.ProviderName %>"

SelectCommand="SELECT country_id, Country_names FROM lu_countries">

</asp:SqlDataSource>

Private Sub rgCountries_UpdateCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles rgCountries.UpdateCommand

        Dim editItem As GridDataItem = e.Item

        'Pass the parameter values to the SqldataSource

         oDSMySqlCountries.UpdateParameters.Add(New Parameter("list_of_countries"))



         oDSMySqlCountries.UpdateParameters("list_of_countries").DefaultValue = GetCheckedItems(DirectCast(editItem.FindControl("rdComboCountries"), RadComboBox))

        'Update the values

        oDSMySqlCountries.Update()

        'Bind the RadGrid again

        rgCountries.Rebind()

End Sub



Private Function GetCheckedItems(ByVal comboBox As RadComboBox) As String

        Dim sb As New StringBuilder()

        Dim collection As IList(Of RadComboBoxItem) = comboBox.CheckedItems



        For Each item As RadComboBoxItem In collection

            sb.Append(item.Value + ", ")

        Next

         Return sb.ToString.TrimEnd(" ").TrimEnd(",")

     End Function

Gantt : ActiveRegionUrl

Hi there,

I am trying to use the Gantt Chart to bind to a custom DataSource. I then want the click event to navigate to a new URL (passing in the ID of the element that has been clicked). Using ActiveRegionUrl='<%# Eval("RecordId", "campaignviewer.aspx?CampaignID={0}") %>' I get a message about the ChartSeries not having a DataBind method.

I have also tried this by interrogating the ClickEventArgs on click, but cannot seem to get any sensical information from it (or set anything for that matter).

Finally, I tried it without using automatic databinding as follows:

foreach (CampaignHeader campaignItem in oCH)

{

ChartSeriesItem chartItem = new ChartSeriesItem();

chartItem.ActiveRegion.Url = string.Format("campaignviewer.aspx?CampaignId={0}", campaignItem.RecordId);

chartItem.Name = campaignItem.CampaignName;

chartItem.YValue = campaignItem.OAStart;

chartItem.YValue2 = campaignItem.OAEnd;

rcCampaign.Series[0].Items.Add(chartItem);

}

However in this way, I cannot set the label for each row and I also see a load of empty rows (labelled from 1 - 10).

Any help would be gratefully appreciated!

Alec.

RadFileExplorer Grid rebind is not working

Hi All,

We have a FileExplorer in our application which is built dynamicallly. On click of a tree node, we are trying to rebind the grid with the value of the node clicked. The datasource of the grid has the updated data but after the code passes rebind statement, the grid still holds the old value. Below is our PopulateGrid() method and it is invoked in OnPreRender.

public void PopulateGrid()
        {
            try
            {
                DataTable dtDocList = new DataTable();
                dtDocList = createDataTable(dtDocList);
                DataRow docListRow = null;

                if (FileExplorerDataSource.Count > 0)
                {
                    foreach (DMSDocument currentDoc in FileExplorerDataSource)
                    {
                        docListRow = dtDocList.NewRow();
                        foreach (AspenDocumentListWebControlShowColumnsConfigurationElement column in AspenDocumentListUIConfig.ColumnsToShow)
                        {
                            foreach (DMSMetadata currProperty in currentDoc.Properties)
                            {
                                if (currProperty.Name == column.DataField)
                                {
                                    docListRow[column.Name] = currProperty.Value;
                                    break;
                                }
                            }
                        }

                        if (String.IsNullOrEmpty(filterExpression))
                        {
                            dtDocList.Rows.Add(docListRow);
                        }
                        else if (docListRow["DocumentType"].ToString() == filterExpression.ToString())
                        {
                            dtDocList.Rows.Add(docListRow);
                        }

                    }
                    if (String.IsNullOrEmpty(filterExpression))
                    {
                        Documents = dtDocList;
                        DataView sortedDocListView = new DataView(dtDocList);
                        if (dtDocList != null)
                        {
                            sortedDocListView.Sort = dtDocList.Columns["CreationDate"] + " DESC";
                        }
                        docListGrid.DataSource = sortedDocListView;
                        docListGrid.DataBind();
                    }
                    else
                    {
                        DataView sortedDocListView2 = new DataView(dtDocList);
                        if (dtDocList != null)
                        {
                            sortedDocListView2.Sort = dtDocList.Columns["CreationDate"] + " DESC";
                        }
                        //docListGrid.SortExpressions.Clear();
                        docListGrid.DataSource = sortedDocListView2;
                        docListGrid.Rebind();
                    }
                }
                else
                {
                    //docListGrid.MasterTableView.NoRecordsTemplate = new NoRecordsTemplate();
                }
            }
            catch (Exception)
            {
                // LogError(ex.Message + " /n Stack Trace :" + ex.StackTrace);
            }
        }

The filter expression will have the value of the tree node clicked.
This is quite urgent. Any help is very much appriciated.

Thanks in advance.

Fidcontrol usercontrol in ItemCommand

I have a stand alone form used for time entry. i display entries in a radgrid. intead of using the pop up edit form, I just want to prefill some values in my user control to do the edit. I cannot seem to find the control with this code. i have definitely verified the names are correct. It says u is nothing then errors when I try to find a drop down list.

Protected Sub rgTimeslips_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles rgTimeslips.ItemCommand

LogID = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("KeyID")

DocID = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("SONumber")

Label7.Text = LogID & "," & DocID

pnlForm.Visible = True

pnlLogGrid.Visible = False

'set values of Time Entry user control

Dim u As UserControl = TryCast(FindControl("TimeEntry2"), UserControl)

Dim ddlso As DropDownList = TryCast(u.FindControl("ddlSO"), DropDownList)

ddlso.SelectedValue = DocID

Dim SOLogKeyID As HiddenField = TryCast(u.FindControl("SOLogKeyID"), HiddenField)

Dim TimeSlipKeyID As HiddenField = TryCast(u.FindControl("TimeSlipKeyID"), HiddenField)

If DocID = 0 Then

SOLogKeyID.Value = "0"

Problem with GridDateTimeColumn filtering

First excuse my english. I have a grid in my page and a method in a WCF Data Service:

<telerik:RadGrid ID="rgDepartaments" runat="server" AllowPaging="true" AllowSorting="true"

AllowFilteringByColumn="true" PageSize="10" AllowMultiRowEdit="true" OnItemCreated="rgDepartaments_ItemCreated">

<MasterTableView DataKeyNames="IdDepartament" ClientDataKeyNames="IdDepartament" CommandItemDisplay="Bottom">

<Columns>

<telerik:GridBoundColumn UniqueName="Departament" DataField="Departamento" DataType="System.String">

</telerik:GridBoundColumn>

<telerik:GridDateTimeColumn UniqueName="UpdateDate" DataField="UpdateDate"

DataType="System.DateTime" DataFormatString="{0:dd/MM/yyyy HH:mm}" HeaderStyle-Width="150px">

</telerik:GridDateTimeColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<DataBinding Location="~/DesktopModules/Comun/Services/DepartmentSvc.svc" SelectCountMethod="TotalDepartments">

<DataService TableName="Departament" />

</DataBinding>

</ClientSettings>

</telerik:RadGrid>

[WebGet]

public int TotalDepartments(string where)

{

return String.IsNullOrEmpty(where) ? this.CurrentDataSource.Department.Count() : this.CurrentDataSource.Department.Where(where).Count();

}

I have 2 problems:
1- When the TotalDepartments is executed with a where condition having a UpdateDate filter I get the following error: Edm.DateTime and Edm.String are not compatible types.

2.- The grid contains 5 records with UpdateDate (21/07/2011 --> 21st July 2011). When I try to filter through UpdateDate width 16/07/2011 and "major than" I get no record (all records must have been returned). By if I filter with 16/07/2001 and "less than" I get all the records (no record must have been returned).

Where is the problem?, Maybe the culture or the DataFormatString?. I've been looking in Google but I can get no answer.

Thanks in advance.
