GridView edit mode takes numeric values only

[Pooran]

For some strange reason, the gridview edit mode for a column that is string binded, accepts only numeric values. What could be wrong

 <telerik:RadGridView Name="rgvSiteDetails" Margin="10,10,10,10" Height="340" RowIndicatorVisibility="Collapsed"
                    ShowGroupPanel="False" AutoGenerateColumns="False" Visibility="Visible" Background="Transparent"
                    AutoGenerateHierarchyFromDataSet="False" BorderBrush="LightGray" CanUserFreezeColumns="False" CanUserInsertRows="False"
                    HorizontalContentAlignment="Stretch" ShowColumnHeaders="True" IsFilteringAllowed="False"
                    VerticalGridlinesBrush="LightGray" >
                    <telerik:RadGridView.Columns>
                        <telerik:GridViewDataColumn UniqueName="IsSelected" DataMemberBinding="{Binding IsSelected}" Header="" Width="30" />
                        <telerik:GridViewDataColumn UniqueName="SiteSequence" Header="" Width="30" DataMemberBinding="{Binding SiteSequence}" />
                        <telerik:GridViewDataColumn UniqueName="SiteName" Header="SiteName" DataMemberBinding="{Binding SiteName}"  Width="120" />
                        <telerik:GridViewDataColumn UniqueName="SiteShortName" Header="SiteShortName" DataMemberBinding="{Binding SiteShortName}"  Width="120"/>
                        <telerik:GridViewDataColumn IsReadOnly="True" UniqueName="ReceivedDate" IsVisible="True" Header="Received Date" Width="80"  DataMemberBinding="{Binding ReceivedDate}"  />
                        <telerik:GridViewDataColumn IsReadOnly="True" UniqueName="PatientLastName" Header="Patient Last Name" IsVisible="True" Width="120"  DataMemberBinding="{Binding PatientLastName}"  />

                        <telerik:GridViewDataColumn x:Name="gdcCassetteId" UniqueName="CassetteID" IsVisible="False" Header="Cassette Id" Width="80"  DataMemberBinding="{Binding CassetteID}" />

                        <telerik:GridViewDataColumn x:Name="gdcSlideId" UniqueName="DisplayName" Header="Display Name" IsVisible="False" DataMemberBinding="{Binding DisplayName}"  />
                        <telerik:GridViewDataColumn x:Name="gdcDisplayName" UniqueName="DisplayName" Header="Display Name" IsVisible="False" DataMemberBinding="{Binding DisplayName}"  />
                        <telerik:GridViewDataColumn x:Name="gdcProcedureName" UniqueName="ProcedureName" Header="Procedure Name" IsVisible="False" DataMemberBinding="{Binding DisplayName}"  />
                        <telerik:GridViewDataColumn x:Name="gdcLevelInfo" UniqueName="LevelInfo" Header="Level Info" IsVisible="False" DataMemberBinding="{Binding DisplayName}"  />
                        <telerik:GridViewDataColumn x:Name="gdcmagazineid" UniqueName="magazineid" IsVisible="False" Header="Magazine Id"  DataMemberBinding="{Binding magazineid}"  />
                        <telerik:GridViewDataColumn x:Name="gdcbin" UniqueName="bin" Header="Exit Bin" IsVisible="False"   DataMemberBinding="{Binding bin}"  />

                    </telerik:RadGridView.Columns>
                </telerik:RadGridView>

Below is the code behind

private void rgvSiteDetails_CurrentCellChanged(object sender, GridViewCurrentCellChangedEventArgs e)
        {
            this.rgvSiteDetails.BeginEdit();
        }

 SharedData.lstSelectedCaseData = new ObservableCollection<SharedData.SelectedCaseData>();

                rgvSiteDetails.DataLoaded += new EventHandler<EventArgs>(rgvSiteDetails_DataLoaded);
               foreach (CaseDataCase item in SharedData.objCurrent.Items)
                        {
                            if (item.Specimen != null)
                                foreach (CaseDataCaseSpecimen item2 in item.Specimen)
                                {
                                    SharedData.SelectedCaseData a = new SharedData.SelectedCaseData();
                                    a.CaseId = item.CaseId;
                                    a.AccessionNumber = item.AccessionNumber;
                                    a.ReceivedDate = item.ReceivedDate;
                                    a.PatientLastName = item.Patient[0].PatientLastName;
                                    a.IsSelected = true;
                                    a.SiteName = item2.SiteName;
                                    a.SiteSequence = item2.SiteSequence;
                                    a.SiteShortName = item2.SiteShortName;
                                    a.SiteID = item2.SiteID;
                                    SharedData.lstSelectedCaseData.Add(a);
                                }

                        }
                        rgvSiteDetails.ItemsSource = SharedData.lstSelectedCaseData;

void rgvSiteDetails_DataLoaded(object sender, EventArgs e)
        {
            try
            {
                SharedData.Log.Info("Entering rgvSiteDetails_DataLoaded");
                rgvSiteDetails.ExpandAllGroups();
                SharedData.Log.Info("Exiting rgvSiteDetails_DataLoaded");
            }
            catch (Exception ex)
            {
                SharedMethods.HandleExceptions(ex);
            }

        }

Any help would be highly appreciated.

Hi Pooran,

 Can you post more info about the exact column which is causing this problem + column binding property declaration?

All the best,

My mistake.. there was one piece of code which was for other textbox.

        protected override void OnPreviewTextInput(System.Windows.Input.TextCompositionEventArgs e)
        {
            try
            {
                SharedData.Log.Info("Entering OnPreviewTextInput " + e.Text);
                e.Handled = !AreAllValidNumericChars(e.Text);
                base.OnPreviewTextInput(e);
                SharedData.Log.Info("Exiting OnPreviewTextInput");
            }
            catch (Exception ex)
            {
                SharedData.Log.Info("Error in OnPreviewTextInput");
                SharedMethods.HandleExceptions(ex);
            }

        }

        private bool AreAllValidNumericChars(string str)
        {
            try
            {
                SharedData.Log.Info("Entering AreAllValidNumericChars " + str);
                foreach (char c in str)
                {
                    if (!Char.IsNumber(c)) return false;
                }
                SharedData.Log.Info("Exiting AreAllValidNumericChars");
                return true;
            }
            catch (Exception ex)
            {
                SharedData.Log.Info("Error in AreAllValidNumericChars");
                SharedMethods.HandleExceptions(ex);
                return false;
            }

        }

I think this function was also used by textbox of telerik gridview. Ideally speaking it should not.. but it is.

I have commented the above said function for now and it works.

Thanks for the pitching in for helping :)
