Hello Sir,

         I'm using radgrid and filtering is done in the grid.
But the filtering is not working properly for the date field
and one more thing, if there is no date value  in a row
its also creating error.

Give me a solution for this.
     thanks in advance

Hello,

I tried to replicate the issue with the filtering you depicted in a sample project based on this demo but unfortunately to no avail. Can you please outline the differences between your grid configuration and the one used in the live example? They can help us determine the reason for the erroneous behavior and how to address it.

Hello sir,

First of all i'm thanking you for the attention that you have
made to my problem.

It works fine in the demo but unfortunately it doesn't
work as expected in the demo in my code.

Here's the code
 <telerik:RadGrid ID="gvDiseaseGrid" runat="server" AllowPaging="True"
                        AllowSorting="True" AutoGenerateColumns="False" GridLines="None"
                        ondeletecommand="gvDiseaseGrid_DeleteCommand"
                        onitemdatabound="gvDiseaseGrid_ItemDataBound"
                        onpageindexchanged="gvDiseaseGrid_PageIndexChanged"
                        onpagesizechanged="gvDiseaseGrid_PageSizeChanged"
                        onselectedindexchanged="gvDiseaseGrid_SelectedIndexChanged"
                        onsortcommand="gvDiseaseGrid_SortCommand" style="margin-bottom: 0px"
                        AllowFilteringByColumn="True" onitemcommand="gvDiseaseGrid_ItemCommand" Height="170px">
                        <MasterTableView DataKeyNames="DisPKey" PageSize="5">
                            <Columns>
                                <telerik:GridBoundColumn DataField="disease" HeaderText="Disease"
                                    UniqueName="disease" AllowFiltering="true">
                                </telerik:GridBoundColumn>
                                 <telerik:GridDateTimeColumn DataField="startdate" HeaderText="Start Date"
                                    UniqueName="startdate" DataFormatString="{0:dd-MMM-yyyy}" AllowFiltering="true">
                                </telerik:GridDateTimeColumn>                                
                                
                                <telerik:GridDateTimeColumn DataField="enddate" HeaderText="End date"
                                    UniqueName="enddate" DataFormatString="{0:dd-MMM-yyyy}" AllowFiltering="true"
                                    PickerType="DatePicker"  SortExpression="enddate" >
                                </telerik:GridDateTimeColumn>    
                                <telerik:GridBoundColumn DataField="medNote" HeaderText="Medical Notes"
                                    UniqueName="medNote">
                                </telerik:GridBoundColumn>
                                <telerik:GridTemplateColumn UniqueName="Sel" AllowFiltering="false">
                                    <ItemTemplate>
                                        <mm:mmImageButton ID="imgbtnSel" runat="server" CommandName="select"
                                            ImageUrl="~/Images/deselect.GIF" Text="mmImageButton" ToolTip="Select" />
                                    </ItemTemplate>
                                    <ItemStyle Height="5px" Width="5px" />
                                </telerik:GridTemplateColumn>
                                <telerik:GridButtonColumn ButtonType="ImageButton" CommandArgument="Delete"
                                    CommandName="Delete" HeaderTooltip="Delete" ImageUrl="~/Images/delete.gif"
                                    Text="Delete" UniqueName="imgbtnDel">
                                    <ItemStyle Height="5px" Width="5px" />
                                </telerik:GridButtonColumn>                               
                            </Columns>
                        </MasterTableView>
                        <ClientSettings Scrolling-AllowScroll="true"></ClientSettings>
                    </telerik:RadGrid>


I tried with the eg provided in the demo but no result.

Thanks in advance

Hi,

I followed your scenario in order to replicate the issue, but to no avail.
Please find attached a simple working project that demonstrates the needed approach. Give it a try and let me know if it works for you.

Hello Sir,

the attached working project did run with the required feature.
i had done the same thing with only one difference is that
I'm binding the datasource of the grid in the server side that
was the only difference i had seen and here's the function
for databinding


protected void radGrid_ItemCommand(object source, GridCommandEventArgs e)
    {
       
        if (e.CommandName == RadGrid.FilterCommandName)
        {          
               DataTable dtGrid = this.oFdrDiseaseChart.FillDiseaseGrid();
               this.radGrid.DataSource = dtGrid;
               this.radGrid.DataBind();
         }
   }

Is there any problem with this type  of binding .
but all other filtering except the date column works
fine.

give me the steps for solving the pblm.




Thanks in advance
Unni

Hello,

Please have in mind that simple data-binding through the DataBind() method can be used in simple scenarios which do not require the grid to perform complex operations such as filtering. I suggest you switch to advanced binding with NeedDataSource event handling and let me know if you need additional assistance.

All the best,

Hello Sir,


 As per your advice I tried to  bind grid  with NeedDataSource event handling
but the date filtering problem still exists.

Please help me. I don't know what's wrong.

Thanks in advance
