Dear All

I built a custom control using asp.net gridview all is working fine but I can not hide/remove white border around each row cell as well as entire gridview boundary, so that my control seems awkward. Please help me how can I achieve this.

I posted sample code below.

<br />
<asp:gridview id="gv_MostPopDeal" runat="server" datasourceid="MostPopDealDataSource" autogeneratecolumns="False" allowpaging="True" pagesize="5" gridlines="None" borderstyle="None" cellspacing="1" borderwidth="0" font-bold="true" bordercolor="White" backcolor="White" font-size="Medium" rowstyle-borderstyle="None" rowstyle-bordercolor="White" rowstyle-backcolor="White" rowstyle-borderwidth="0" xmlns:asp="#unknown"><br />
            <columns><br />
            <asp:boundfield headertext="Merchant Name" datafield="FLL_NM" />         <br />
          <br />
           <asp:hyperlinkfield headertext="Click Below for details" datatextfield="OFR_TTL" datanavigateurlfields="RTLR_ID,PRMTN_ID" datanavigateurlformatstring="PromotionOfferDetials.aspx?retlrid={0}&prmtnid={1}" /><br />
                            <br />
            </columns><br />
                <rowstyle borderstyle="None" font-names="Book Antiqua" /><br />
            </asp:gridview><br />

Thank you.

Make cellspacing="0" and cellpadding="0" and check
also remove the bordercolor="White" if you don't require and check

I am creating on custom control.I have problem to create bubble event of that control.

Here is my code,In which I added one button control

protected override void RenderContents(HtmlTextWriter writer)
        {
					.....................
					Button btn = new Button();
                                        btn.Text=_updateTemplate.Text;
                                        btn.ID = "ExelDataGrid_" + j.ToString() + i.ToString();
                                        btn.CommandArgument = _rows[i - 1].ToString();
                                        btn.CommandName = "update";
                                        
                                        btn.RenderControl(writer);
					...................
	}

I have defined event

public event EventHandler Updating;

I am calling this method when buble event rise

protected virtual void OnUpdating(EventArgs e)
        {
            Updating(this, e);
        }
        protected override bool OnBubbleEvent(object source, EventArgs args)
        {
           OnUpdating(args);
           return true;
        }

Now when I use this control on my web application,then OnUpdating event doesn't call on button click event.
Can Anyone give me suggetion to solve this issue?

If I add button click event then also does not work.
Here is my code

public void btn_Click(object sender, EventArgs e)
        {
            this.RaiseBubbleEvent(sender, e);

            //OnUpdating(e); // In this case also its not working.
        }

.........
btn.Click += new EventHandler(btn_Click);
                                        btn.RenderControl(writer);
...........

If you want a pause, you need to turn the images off an one in your move over and mouse out events.

How to hide/show a button in a gridview depending on the userid and 'role'

Apr^Ngp11-Aug-08 22:44

11-Aug-08 22:44

I am having a page on which a grid view is displaying some message posted by the users.
The messages are stored in the database in a table having columns for MessageId,UserId and Message.
Now i want to add buttons like, 'Edit' / 'Delete' (after displaying every message)which will be visible to only the author of that message and to the administrator.
Using that button, the users shall be able to edit/delete the message.
I am able to add those buttons, but how to make them visible/invisible depending on the userid and the 'role' in which the user is logged in.
Please help ...

Whats the problem with the button being disabled for all rows?

I thought that was what you wanted and then you can check if the user is normal or admin and depending on which display or hide the button using the code I posted

use the ID of the button.
Put the code in your c#, so for example here is mine:

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (Common_methods.userPermission("admin") == false)
{
((CheckBox)e.Row.FindControl("buttonid")).Visible = false;
}
}
}

then use onrowcreated method for your gridview
make sense?

Its working perfectly friend ...
BUT the person who has posted the message shall be able to edit/delete it ...
While loading the messages from the database to the gridview, the userid is also loaded ...
is there any way, by which when the row is created in the gridview, and the corresponding event handler is called, the userids can be compared ...

Style.Add performance

Hi !

Is there any known performance issues concerning run-time manipulation with Style object ?

I used ANTS profiler to profile my application and suddenly found that the following Style.Add statement is one of the slowests:

<br />
       tb = (Table)this.FindControl("ContentTable");<br />
       if (tb != null)<br />
       {<br />
           if (this.Language == InputLanguage.Hebrew)<br />
           {<br />
               tb.Style.Add(HtmlTextWriterStyle.Direction, "rtl");<br />
<br />
           }<br />
           else<br />
           {<br />
              tb.Style.Add(HtmlTextWriterStyle.Direction, "ltr"); <br />
           }<br />
        }<br />
<br />

If those performance issues are exist, is there any work around?

Thanks in advance.
Regarads,
Gennady

It should not have much performance issue just you are changing the style
Is the Page is very complex and big in size ? then it may take some time
to locate your ContentTable(not considerable time).
i don't think it is going to have performance issue.
This is what i think.
Any inputs from others ?

Thanks and Regards

I agree.
But still if you feel that it is an over head. Another solution may be to pass your language name to the javascript and change the style at the client side itself.

Hi !

Page is not too complex. And findcontrol takes significantly less time:

FindControl - 0.0083
Style.Add - 0.606

As for passing this action to the client - I considered this alternative way, but first I'd like to understand - what is going wrong on the server side.

Thanks.

Gennady
