We are evaluating the Grid and will need to access the grid in an unbound fashion, adding, hiding rows, columns, etc as well as getting and setting the values of specific cells from both the client and/or server side at run time.

Is this possible?  Does anyone have a quick and easy sample of how to do this?

This is default page code:
protected void grdFiles_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.DownloadAttachmentCommandName)
        {
            
                GridDownloadAttachmentCommandEventArgs args = e as GridDownloadAttachmentCommandEventArgs;
                string fileName = args.FileName;
                int attachmentId = (int)args.AttachmentKeyValues["ProjectFileId"];
                ProTrakEntities objEntity = new ProTrakEntities();
                ProjectFile objFile = (from type in objEntity.ProjectFiles where type.ProjectFileId == attachmentId select type).First();
                string filename = objFile.FileName;
                string Filetype = objFile.FileType;
                byte[] binaryData = (byte[])objFile.FileData;
             
                Response.Clear();
                Response.ContentType = Filetype;
                Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
                Response.BinaryWrite(binaryData);
                Response.End();
            
        }
    }

**Uploaded file Code**
 protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
    {
        if (DetailsView1.CurrentMode == DetailsViewMode.Insert)
        {
            if (Session["ProjectId"] != null)
            {
                int Projectid = Convert.ToInt32(Session["ProjectId"]);
                string Description = (DetailsView1.FindControl("RadEditor1") as RadEditor).Content;
                RadAsyncUpload radAsyncUpload = DetailsView1.FindControl("RadAsyncUpload1") as RadAsyncUpload;
                UploadedFile file = radAsyncUpload.UploadedFiles[0];
                string s = file.FileName;
                string path = System.IO.Path.GetFileName(s);
                    string Contenttype = radAsyncUpload.UploadedFiles[0].ContentType;
                int fileSize = radAsyncUpload.UploadedFiles[0].ContentLength;
                float length = float.Parse(fileSize.ToString());
                byte[] fileData = new byte[file.InputStream.Length];
                file.InputStream.Read(fileData, 0, (int)file.InputStream.Length);
                        ProTrakEntities objEntity = new ProTrakEntities();
                        ProjectFile objFile = new ProjectFile();
                        objFile.ProjectId = Projectid;
                        objFile.FileName = s;
                        objFile.FileType = Contenttype;
                        objFile.FileSize = length;
                        objFile.CreatedBy = "admin";
                        objFile.CreatedDate = DateTime.Now;
                        objFile.Description = Description;
                        objFile.FileData = fileData;
                        objEntity.AddToProjectFiles(objFile);
                        objEntity.SaveChanges();
                
            }
         }
    }
I'm saving the data in database in binaryfromat.i data was not downloading from sever when i click the attachmentcolumn.

Hi,

I am trying to set the values for Between filter in the PreRender event of the grid..
Filter works fine if I  pass a single value (int)
But I need to pass a range of values and use "Between" filter. Tried couple of syntaxes given below but did not work. Can you please let me know what am I doing wrong?

 

Hello guys,

I'm facing a problem with the RadTab component on IE 9 and Mozilla 5. In the other versions of IE, its behavior is ok. Don't know about other Mozilla versions. Follows more info about the issue.

I have a RadTab and a MultiPage. RadTab is linked with the MultiPage. I want a VerticalLeft RadTab, but, in these new versions, the RadTab persists at the top of the multipage and is showing as HorizontalTab. On other versions, it is working as expected. I've tried some CSS combinations, but none of them worked as expected.

Follows the code:

 

<telerik:RadTabStrip ID="rtsVertical" runat="server" MultiPageID="rmpCourseEdit"

SelectedIndex="1" SkinID="OutlookVTAB" Style="float: left">

<Tabs>

<telerik:RadTab Text="pgvBasic" PageViewID="pgvBasic" runat="server" Selected="True" /

<telerik:RadTab Text="pgvComposite" PageViewID="pgvComposite" runat="server" />

<telerik:RadTab Text="pgvTexts" PageViewID="pgvTexts" runat="server" />

<telerik:RadTab Text="pgvPub" PageViewID="pgvPub" runat="server" />

<telerik:RadTab Text="pgvSpec" PageViewID="pgvSpecialist" runat="server" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="rmpCourseEdit" runat="server" SelectedIndex="0" RenderSelectedPageOnly="false" CssClass="MultiPageV">
... </>

Follows the CSS and Skins:
<telerik:RadTabStrip runat="server" SkinID="OutlookHTAB"

 Skin="Outlook"

 EnableEmbeddedSkins="False"

 Orientation="HorizontalTop"

 />

-------------------------

Can you help me with this guys?

tks,

 

I have a grid ( radGridDocs ) when the user clicks a linkbutton in the grid (which is in the UC, DocumentAccess) the modal window pops up and the client can enter their comments. When they are finished entering their comments and click submit, the desired behavior is for the window (docComments) to close and refresh the grid. I assume this will be done via Java script, but I am new to java scripting and require a little help.

Thanks,
Chuck

Update:

Telerik Please close this issue. I was able to able to fix it as suggested by Princy.

Basically, in Pre-Render event I hide the Default Expand/Collapse Column and rest I followed based on below link.

Folks using VS 2010 with RadGrid for ASP.Net Ajax 2011 V2.

I have a Hierarchical grid, Master Table HierarchyLoadMode="Client".

If use use expand/collapse Expand/Collapse ImageUrl from a File via ColumnCreated event, I got the attached error message while exporting to PDF. But If i do not call Column created event in Radgrid thus by using default Expand/Collapse ImageURL, the PDF export works fine. Also if  I use HierarchyLoadMode=Server or ServerOnDemand and call ColumnCreated event, export works fine. 
 
Any help appreciated..

Thanks

Hi guys,
I have following code in my aspx page:

<

 

tr>

 

 

<td >

 

 

<p class="style" >

 

Please enter job posting number:

 

</p>

 

 

</td>

 

 

<td >

 

 

<telerik:RadNumericTextBox ID="JobPostingNo" runat="server" TabIndex="9" Font-Bold="true" MaxLength="4" Type="Number" MinValue="1" MaxValue="9999" CssClass="textbox" Width="48px" Enabled="false">

 

 

<NumberFormat GroupSeparator="" DecimalDigits="0" />

 

 

<DisabledStyle Font-Bold="true" BackColor="#EFEFEF" />

 

 

</telerik:RadNumericTextBox>

 

 

</td>

 

 

<td>

 

 

<asp:Image ID="JobPNErrImage" runat="server" Width="14px" Height="14px" ImageUrl="~/Image/error-icon.jpg" Visible="false" />

 

 

</td>

 

 

 

</tr>

 

 

<tr>

 

 

<td>

 

 

<p class="style">

 

Have you met all of the criteria outlined in the posting?

 

</p>

 

 

</td>

 

 

<td>

 

 

<telerik:RadComboBox ID="ddlPost" runat="server" TabIndex="10" AutoPostBack="false" Font-Size="Small" Width="53px">

 

 

<Items>

 

 

<telerik:RadComboBoxItem Text="Select" Value="" Selected="true" />

 

 

<telerik:RadComboBoxItem Text="Yes" Value="Y" />

 

 

<telerik:RadComboBoxItem Text="No" Value="N" />

 

 

</Items>

 

 

</telerik:RadComboBox>

 

 

</td>

 

And here is a code behind file:

RadPanelBar

 

attestPanel = (RadPanelBar)formPanel.FindItemByValue("principalForm").FindControl("attestationPanel");

 

 

RadNumericTextBox jobPostNo = (RadNumericTextBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("JobPostingNo");

 

 

RadComboBox ddlAprvPost = (RadComboBox)attestPanel.FindItemByValue("principalattestaionInfo").FindControl("ddlAprv");

 

 

if (ddlAprvPost.SelectedValue == "Y")

 

{

jobPostNo.Enabled =

true;

 

jobPostNo.Focus();

}

 

else

 

{

 

if (jobPostNo.Text.Length > 0)

 

{

jobPostNo.Text =

string.Empty;

 

}

jobPostNo.Enabled =

false;

 

 

}

My question is: when jobPostNo control is disabled how  to shift focus to the next control right after this control.

Thanks so much.

I would be grateful for an example of how to wire-up some client-side javascript to the click event on a GridHyperlinkColumn. I have this markup:

 

 

 

 <MasterTableView>
 
<Columns>
 
<telerik:GridBoundColumn DataField="id" Visible="false" DataType="System.Int32"></telerik:GridBoundColumn>
 
<telerik:GridHyperlinkColumn DataTextField="companyname" DataNavigateUrlFields="companyURL" datatype="System.String">
 
</telerik:GridHyperlinkColumn>
 
</Columns>
 
</MasterTableView>

 

 

 

 

 

 

and I want to send the value of the DataNavigateUrlFields to a client-side javascript function when the hyperlink is clicked:

someClientSideFunction(  value of the DataNavigateUrlFields of the clicked item );

Thanks

Folks,

I am using ASP.Net Ajax Q2 2011 with VS 2010. Below is my Grid Table Laout.

        
        Parent Table

                                ---- Detail Table 1 (GridTableView Name = "Detail")

                                             --- Detail Table 1.1

                                ---- Detail Table 2

　
My desired expectations:

1) While I am scrolling rows in Parent Table, I would like to get the row counts of related Detail Table 1 but not row counts of other Detail Tables.

2) Also if I am scrolling rows in Detail Table 1, do nothing.
 

Below works to get the Row Count of Parent Table; but having some difficulty to getting row count of Related Detail Table 1.
