[Solved] value of GridEditableItem["File"] is &nbsp which is empty space

[Ghouse]

I upgraded to new Telerik version 2013.1.220.35 from 2010.3.1109.35. and compatibility issues started...

 

<telerik:RadGrid runat="server" ID="FileListView" AutoGenerateColumns="false" Skin="Windows7" 

Width="100%" OnDeleteCommand="FileListView_DeleteCommand">

<MasterTableView>

<Columns>

<telerik:GridButtonColumn UniqueName="DeleteColumn" ButtonType="ImageButton" CommandName="Delete"

ConfirmTitle="Confirm" ConfirmText="Continue deleting file?" /> <telerik:GridBoundColumn UniqueName="file" DataField="file" Visible="false" ReadOnly="true" />

 <telerik:GridBoundColumn UniqueName="Attachedfiles" DataField="Attached files" HeaderText="File" />

 <telerik:GridBoundColumn UniqueName="Attachedby" DataField="Editor" HeaderText="Attached by" />

 <telerik:GridBoundColumn UniqueName="Attachedat" DataField="Modified" HeaderText="Attached at" />

 </Columns>

 </MasterTableView>

 </telerik:RadGrid>

 

protected void FileListView_DeleteCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

 {
GridEditableItem editedItem = e.Item as GridEditableItem;

 string filename = editedItem["file"].Text;
logic continues...

but in the above code filename has &nbsp as the value. means filename contains empty space as it value instead of actual file name

Please suggest.

Hi,

The value is returning "&nbsp" because Visible property is set as false. Try setting Display property instead and access the value.
aspx:

<telerik:GridBoundColumn UniqueName="file" DataField="file" Display="false" ReadOnly="true" />

Thanks,
Shinu

Sir:
My code as below, but name still get "&nbsp;",I don't know what happened. 
foreach (GridEditableItem editedItem in (fvESD1.FindControl("GvFieldValue") as RadGrid).EditItems) //將CbCategoryName未選擇欄位隱藏
            {
                
                         string name = editedItem["Name"].Text.Trim();
                         if ((fvESD1.FindControl("CbCategoryName") as RadComboBox).SelectedValue != name)
                        {
                             editedItem.Attributes.Add("style", "display:none");
                                                        
                        }
                    }
               
            }

Hi,

I'm not clear about your requirement, I guess you want to access values in edit mode on a button click. Please try the below code snippet. If this doesn't help, elaborate on your requirement and provide your aspx page also.

ASPX:

<telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity" Display="false" />
<telerik:GridTemplateColumn HeaderText="ShipCountry" DataField="shipCountry">
    <ItemTemplate>
        <%# Eval("ShipCountry") %>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource2" DataTextField="ShipCountry" DataValueField="ShipCountry">
        </telerik:RadComboBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

C#:

//On a button click
protected void btnSave_Click(object sender, EventArgs e)
{
  foreach (GridDataItem item in RadGrid1.EditItems)
  {
    GridEditableItem edititem = (GridEditableItem)item.EditFormItem;
    TextBox txt = (TextBox)edititem["ShipCity"].Controls[0];// Access a bound column in edit
    string name = txt.Text; // gets the text
    RadComboBox combo = (RadComboBox)edititem.FindControl("RadComboBox1");// Access a RadComboBox in template column in edit
    string value = combo.SelectedValue; //gets the selcted value
  }
}

Thanks,
Shinu

Hi,

I guess you want to access the ReadOnly columns in InPlace edit mode. You can set that DataField as DataKeyNames and access it in the code behind as follows:

ASPX:

<MasterTableView DataKeyNames="Name">

C#:

foreach (GridDataItem item in GvFieldValue.EditItems)
{
 string val = item.GetDataKeyValue("Name").ToString();
}

Also take a look at this article on Updating Values Using InPlace and EditForms Modes

Thanks,
Shinu
