Do you set the value of the dropdownlist in (for example) the OnLoad event?

if (!IsPostback)
{
 // Set dropdown values
}

You can place the dropdown list and the control you want to change onselectedindexchanged in update panel control, but place the upload control outside the update panel.

it will surely work for you.

selected indexchange event fires twice when selection changes i.e one event for deselecting the previous item and other for selecting the new item.
you may be refreshing the fileupload control in selected index change event,if so,make sure file upload path is empty before refreshing.

You must specify a date format you want to use to display the date.
This should do the trick :

DateTime.Now.ToString("d MMM yyyy hh:mm:ss");

You can use DateTime.Now.Month to return an int representation of the month. You can pass this to a function to switch on for the month name, IE:

switch(month)
{
case 1:
 return "January";
case 2:
 return "Feburary";
}

Hi there,

is it a bound field? Then you could use the DataFormatString property.

In a custom/template field, you could output your value as string and use string.Format with
a fitting format string (like here).

Hi,

then here is an example on how to do it. Just replace the "((double)0.123)" by your variable and modify the rest according to your needs:

<ItemTemplate>
    <asp:Label runat="server" Text='<%# ((double)0.123).ToString("N") %>'></asp:Label>                   
</ItemTemplate>

maybe it happens because the master page and the pages are placed in different directories...
what can I do?

Dropdownlist not displaying selectedItem in GridView

I have a Gridview in my form and I use SqlDataSource to fill the Grid. I have an Edit button also in the Gridview to Edit data.

The problem is while clicking on Edit, the dropdownlist in the Gridview
is not displaying the item selected, but going to the first item of the dropdownlist. How should I make the selected item
displayed while click on Edit?

Please find below my code:

<asp:GridView ID="grdDTCCRics" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False"

            <asp:BoundField  DataField="REDCODE" HeaderText="REDCODE" ReadOnly="True" SortExpression="REDCODE" />

                    </asp:DropDownList>
                </EditItemTemplate>
                    <ItemTemplate>            
                        <asp:Label ID="lblcountry" runat="server" Text = '<%# Eval("REGIONCODE") %>'></asp:Label>

              <ControlStyle Height="22px" Width="50px" />
                   </Columns>
</GridView>

When I tried to get the editrowindex, the object lstRegion is coming as null in the rowEditing eventhandler. Any idea how to display it properly? Please help.

Thanks

Hi,

maybe there is a simpler solution, but you could use the rowdatabound event
of your gridview and set the index of the dropdown there appropriatly (if in edit mode).

Here is an example (which is using c1gridview, just replace it by the microsoft one and
check the if conditions, they may be slightly different)

protected void grdRoomTypes_RowDataBound(object sender, C1.Web.UI.Controls.C1GridView.C1GridViewRowEventArgs e)
{

    if (e.Row.RowType == C1.Web.UI.Controls.C1GridView.C1GridViewRowType.DataRow)
    {
        if ((e.Row.RowState & C1.Web.UI.Controls.C1GridView.C1GridViewRowState.Edit) > 0)
        {
            // here find your dropdownlist by id and set the index
            TimeSchemeEditor editor = (TimeSchemeEditor)e.Row.FindControl("timeSchemeEditor");
            editor.TimeScheme = (ServiceDirectoryRoomTypeItem)e.Row.DataItem;
        }
        else
        {
            // Do nothing here maybe
            TimeSchemeViewer viewer = (TimeSchemeViewer)e.Row.FindControl("timeSchemeViewer");
            viewer.TimeScheme = (ServiceDirectoryRoomTypeItem)e.Row.DataItem;
        }
    }
}

Thanks for the reply. However that code is not working. Following is my RowDataBound Event:

protected void grdTCCRics_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            
            if ((e.Row.RowState & DataControlRowState.Edit) > 0)
            {
                //grdDTCCRics.EditIndex = e.Row.RowIndex;
                //grdDTCCRics.DataBind();
               
                Label lblRegion = (Label)e.Row.FindControl("lblcountry");

                if (lblRegion != null)
                {
                    DropDownList ddlRegion = (DropDownList)e.Row.FindControl("RegionCodeList");
                    if (ddlRegion != null)
                    {
                        ddlRegion.SelectedItem.Text = lblRegion.Text.Trim();
                    }
                }
            }
        }
    }

The Label control lblRegion is coming as null. So how will I get the value? Please help.

Thanks

I guess in your markup, you have an edititemtemplate and an itemtemplate, is that right?

In your rowdatabound event, it depends on the current rowstate, which controls exist and which not. For example, if you have a label in your itemtemplate and a dropdown in your
edititemtemplate, then the label will be null if rowstate == edit and the other way around.

So first check if RowState == Edit and then find your dropdown. you will not find the
controls shown during "view" rowstate (dont read viewstate:P).

Ok. Thanks a lot Michael. I have EditItemTemplate and ItemTemplate. As you said, I checked now only the dropdownlist and I'm getting the object. But how will I fix the selected value. Still it is displaying only the first value.

<asp:TemplateField HeaderText="REGIONCODE" SortExpression="REGIONCODE">
                <EditItemTemplate>
                    <asp:DropDownList ID="RegionCodeList" runat="Server" AppendDataBoundItems="true" >
                     <asp:ListItem Text="AM" ></asp:ListItem>
                    <asp:ListItem Text="US" ></asp:ListItem>
                    <asp:ListItem Text="EU"></asp:ListItem>
                    <asp:ListItem Text="JP" ></asp:ListItem>
                    <asp:ListItem Text="AS" ></asp:ListItem>
                    <asp:ListItem Text="OF" ></asp:ListItem>
                    </asp:DropDownList>
                </EditItemTemplate>
                    <ItemTemplate>            
                        <asp:Label ID="lblcountry" runat="server" Text = '<%# Eval("REGIONCODE") %>'></asp:Label>
                    </ItemTemplate>
            </asp:TemplateField>

As per the above, it always show the selected value as 'AM' rather than 'EU' which is the actual value selected. Following is my RowDataBoundEvent.

protected void grdTCCRics_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        

        if (e.Row.RowType == DataControlRowType.DataRow)
        {  
            
            if ((e.Row.RowState & DataControlRowState.Edit) > 0)
            {
                DropDownList ddlRegion = (DropDownList)e.Row.FindControl("RegionCodeList");
                if (ddlRegion != null)
                {
                    string strregion = ddlRegion.SelectedItem.Text;
                } 
                
            }
        }

Hi,

you have to set the SelectedIndex of your DropDownList in this event (according
to the value of your DataItem)

Try something like this:

protected void grdTCCRics_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if ((e.Row.RowState & DataControlRowState.Edit) > 0)
                {
                    DropDownList ddlRegion = (DropDownList)e.Row.FindControl("RegionCodeList");
                    if (ddlRegion != null)
                    {
                        // You have to replace VALUEFROMDATAITEM by the current region
                        // value of your DataItem (look in e.Row.DataItem, i dont know it)
                        ListItem item = ddlRegion.Items.FindByValue("VALUEFROMDATAITEM");
                        ddlRegion.SelectedIndex = ddlRegion.Items.IndexOf(item);

                        //string strregion = ddlRegion.SelectedItem.Text;
                        // You dont retrieve the value of the dropdown here, you set it
                    }
                }
            }
        }

I hope this helps
