Dear All,
Can someone please help me with AsyncUpload control inside RadGrid since I am really new with Telerik controls.

I have a DB table with column names as:

RecordID          Name          AttachmentPath
1                       Name1        ~/Attachments/File123_1.pdf
2                       Name2        ~/Attachments/File125_2.pdf

Below are what I did:

1. Inserted RadGrid with its default functionality of Inserting, Editing, and Deleting. (Works Perfect)
2. Inserted AsyncUpload control inside RadGrid for uploading files. (Works Perfect)

3. Fired the OnFileUploaded event to upload control in a path. (Works Perfect)

Below are what I want:

1. While adding new record & uploading file with it, the file should be renamed with the table Record ID of RadGrid as OrignalFileName + "_" + RecordID
2. The FileName from point#1 should be stored in AttachmentPath (DB Column name).
3. While editing a selected record from RadGrid, I should be also able to edit associated file such as delete the file, etc.

Point to be noted, I want only one file to be associated/attached per record.


Thanks In Advance,

Fawad Surosh

Hi,

I have used RadComboBox inside my DetailsView. I send the value of combobox as comma separated to the database as (1,2,3,4). When I want to retrieve the data (1,2,3,4) from the database using SqlDataSource on edit mode of DetailsView, how can I set or bind the "Checked" values and display them as checked back in the combobox.

Here is what i have done:

--> WebForm1.Aspx

<%----------------------- DATA SOURCE FOR DELIVERABLE -------------------------%>
 
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:ITSConnectionString %>"
            DeleteCommand="DELETE FROM [Deliverable] WHERE [DeliverableId] = @DeliverableId"
            InsertCommand="INSERT INTO [Deliverable] ([DeliverableTitle],[CCIds]) VALUES (@DeliverableTitle, @CCIds)"
            SelectCommand="SELECT * FROM [Deliverable] WHERE ([DeliverableId] = @DeliverableId)"
            UpdateCommand="UPDATE [Deliverable] SET [DeliverableTitle] = @DeliverableTitle, [CCIds] = @CCIds WHERE [DeliverableId] = @DeliverableId">
            <DeleteParameters>
                <asp:Parameter Name="DeliverableId" Type="Int32" />
            </DeleteParameters>
            <InsertParameters>
                <asp:Parameter Name="DeliverableId" Type="int32" />
                <asp:Parameter Name="DeliverableTitle" Type="String" />
                <asp:Parameter Name="CCIds" Type="String" />
            </InsertParameters>
            <UpdateParameters>
                <asp:Parameter Name="DeliverableId" Type="int32" />
                <asp:Parameter Name="DeliverableTitle" Type="String" />
                <asp:Parameter Name="CCIds" Type="String" />
            </UpdateParameters>
   <SelectParameters>
      <asp:QueryStringParameter Name="DeliverableId" QueryStringField="DeliverableId" Type="Int32" />
   </SelectParameters>
</asp:SqlDataSource>
 
<%----------------------- DATA SOURCE FOR COMBOBOX -------------------------%>
 
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ITSConnectionString %>" SelectCommand="SELECT [UserId], [DisplayName] FROM [Users]"></asp:SqlDataSource>
 
<%----------------------- THE DETAILS VIEW -------------------------%>
 
<asp:DetailsView ID="DetailsView1" runat="server" DefaultMode="Insert" AutoGenerateRows="False" DataKeyNames="DeliverableId" DataSourceID="SqlDataSource2" Height="50px" Width="125px" OnItemInserting="DetailsView1_ItemInserting" OnDataBinding="DetailsView1_DataBinding" OnDataBound="DetailsView1_DataBound">
            <Fields>
                <asp:BoundField DataField="DeliverableId" HeaderText="DeliverableId" InsertVisible="False" ReadOnly="True" SortExpression="DeliverableId" />
                <asp:BoundField DataField="DeliverableId" HeaderText="DeliverableId" SortExpression="DeliverableId" />
                <asp:BoundField DataField="DeliverableTitle" HeaderText="DeliverableTitle" SortExpression="DeliverableTitle"/>
                <asp:TemplateField>
                    <ItemTemplate>
                     <telerik:RadComboBox ID="CCIds" Text='<% #Bind("CCIds") %>' runat="server"
                         DataSourceID="SqlDataSource1" DataTextField="DisplayName"  DataValueField="UserId"
                         CheckBoxes="true"></telerik:RadComboBox>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:CommandField ShowEditButton="True" />
                <asp:ButtonField Text="Insert" CommandName="Insert" />
                <asp:ButtonField Text="Update" CommandName="Update" />
            </Fields>
        </asp:DetailsView>

--> WebForm1.Aspx.CS

public string GetCheckBoxValues(string RadComboBoxName)
        {
            RadComboBox rcb = (RadComboBox)DetailsView1.FindControl(RadComboBoxName);
            var collection = rcb.CheckedItems;
            StringBuilder sbValues = new StringBuilder();
            if (collection.Count != 0)
            {
                foreach (var item in collection)
                {
                    sbValues.Append(item.Value);
                    sbValues.Append(Delimiter);
                }
                if (sbValues.ToString().EndsWith(Delimiter))
                    sbValues.Remove(sbValues.Length - 1, 1);
            }
            return sbValues.ToString();
        }
         
        // Get the comma separate values and insert them into the DB.
        protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
        {
            string CCIds = GetCheckBoxValues("CCIds");
            if (CCIds != null)
            {
                e.Values["CCIds"] = CCIds;
            }
         }


Now how can I get the comma separated values and bound them with the combobox so that it should check only those items.

is it possible to get radgrid changes on postback? pretty much is there a radgrid equivalent of textbox.text?

Hi,

May i know the code to select out all items in radgrid in all the pages? As sometimes when i do filtering, i need all the items from whole grid (grid with paging) to display in other places.

I cannot use code as below, as it just select out just one page from the grid only.

For Each griditem As Telerik.WebControls.GridItem In radgrid.Items
Next

Please advice.

Thanks,
Soo

Hi,

I am using Telerik Asp.Net for Ajax version 2014.3.1024.40.

I have enabled virtual scrolling the drop down list as below. I am able to see only the Afghanistan, all the others are shown as blank value. However i disable the virtual scrolling, i am able to see all the entries. Please let me know whats the issue and how to fix it ?

<telerik:RadDropDownList ID="rdlCountry" DefaultMessage="---" EnableVirtualScrolling="true"  runat="server"  >
                                                            <Items>
                                                                <telerik:DropDownListItem Text="Afghanistan" />
                                                                <telerik:DropDownListItem Text="Albania"  />
                                                                <telerik:DropDownListItem Text="Algeria" />
                                                                <telerik:DropDownListItem Text="Andorra" />
                                                                <telerik:DropDownListItem Text="Angola" />
                                                                <telerik:DropDownListItem Text="Antigua & Deps" />
                                                                <telerik:DropDownListItem Text="Argentina" />                                                             
                                                            </Items>
                                                        </telerik:RadDropDownList>

In this simple example (found here in the forum) for setting the filtering in code behind I get a "Expression Expected"  error.

I have already set the EnableLinqExpression="false" in the grid.



What are I doeing vrong?

Hi, 
I need to customize telerik slider to obtain something like the attached image.

Any help will be appreciated.
Thank you.

how do you reset a grid, in batch edit mode, to its original state after an update? ie, clear whatever tracked changes it has going on so that if i click save changes again it doesn't still think there are commands to process

when i add an item, save changes, and then edit the same item (or do nothing to it) i get an update command with an oldvalues count of 0 and a null newvalues object. which feels less like an update than a not anything at all. if i could reset the grid after each save changes it wouldn't be an issue

Hi All,

I have IList<Class1>. My Class1 has two property. Say Name and ID Now I want. Dynamic Order By On Both Property.
OrderBy Should Be Ascending or Descending.

How can I achieve this functionality.

I am using this as            
var data = RadGrid.GetBindingData(retval.AsQueryable(), startIndex, maximumRows, sortBy, filterExpressions);

in sort by it only take the property name. so how can specify the sort order.

Please Help

Is there a way to set the height of a multi-row textbox so that it automatically shows it's complete content without scrollbars, but also without unnecessary white space at the bottom?

Reason: I have a page which can be in edit or in read-only mode. In read-only mode, I'd like for all input controls to show their complete content, regardless of the amount of text (e. g. for printing). Is this possible?
