How to access input control of RadAsyncUpload inside RadGrid

[Robin]

Hello all, 

Is there a way to access input control of RadAsyncUpload control from Grid ItemDataBound event?
When grid row is in edit mode, I need to display the file name that user have previously chosen.

I used findControl of RadAsyncUpload control like below. But cannot find child control.

protected void gridMembers_ItemDataBound(object sender, GridItemEventArgs e)
{
            if (e.Item.IsInEditMode)
            {
                RadAsyncUpload ascUpload = e.Item.FindControl("RadAsyncUploadFile") as RadAsyncUpload;
                Control l_Control = ascUpload.FindControl(ascUpload.ClientID.Replace(ascUpload.ID, "file1"));
// null
            }
}

Thanks in advanced,
Robin

Hi Robin,

Please try the following code snippet to get the last uploaded file from RadGrid ItemDataBound  event.

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem edit = (GridEditableItem)e.Item;
        RadAsyncUpload RadAsyncUpload1 = (RadAsyncUpload)edit.FindControl("RadAsyncUpload1");
        string path = Server.MapPath(RadAsyncUpload1.TargetFolder);
        DirectoryInfo targetDir = new DirectoryInfo(path);
        var myFile = targetDir.GetFiles()
            .OrderByDescending(f => f.LastWriteTime)
            .First();
        string name = myFile.Name;
        Label label1 = (Label)edit.FindControl("Label2");
        label1.Text = name;
    }
}

Also you can access input control of RadAsyncUpload either by getElementsByTagName or by getElementsByClassName as follows.

C#:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
        string script = "function f(){GetInput(" + RadAsyncUpload1.ClientID + "); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);
}

JavaScript:

<script type="text/javascript">
    function GetInput(RadAsync) {
        var inputcontrol = RadAsync.getElementsByTagName("<input type='file'>"); // byTageName
                            //or
        var inputcontrol = RadAsync.getElementsByClassName("ruFileInput"); //byClassName
    }
</script>

Thanks,
Princy.

How to insert the file using radasyncupload in radgrid item inserrted command???

Hi Ramkumar,

I guess you want to insert the Uploaded FileName into the DataBase in RadGrid InsertCommand event. Please have a look into the sample code snippet.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="false"
    OnInsertCommand="RadGrid1_InsertCommand" OnItemInserted="RadGrid1_ItemInserted" >
    <MasterTableView CommandItemDisplay="Top">
        <Columns>
            <telerik:GridBoundColumn DataField="OrderID" UniqueName="OrderID" HeaderText="OrderID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="CustomerID" UniqueName="CustomerID" HeaderText="CustomerID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="ShipAddress" UniqueName="ShipAddress" HeaderText="ShipAddress">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn>
                <EditItemTemplate>
                    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server">
                    </telerik:RadAsyncUpload>
                </EditItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
    </MasterTableView>
    <ClientSettings Selecting-AllowRowSelect="true">
    </ClientSettings>
</telerik:RadGrid>

C#:

protected void RadGrid1_InsertCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.Item is GridEditFormInsertItem && e.Item.IsInEditMode)
    {
        GridEditFormInsertItem editItem = (GridEditFormInsertItem)e.Item;
        RadAsyncUpload upload = (RadAsyncUpload)editItem.FindControl("RadAsyncUpload1");
        string filename= upload.UploadedFiles[0].FileName;
            //Query to insert the filename in database
    }
}

Thanks,
Shinu.
