I have binded gridview to database and it loads on TICKER's event. It works good but problem is that when it rebinds then GIRDVIEW's layout and shape becomes improper and disturbed, kinda messed up.

In my web app I have a GridView that gets information from the SQL database then I have a timed event that pings the IP addresses every 5 seconds. If the response is less that 15ms the icon is displayed as a green tick. If more that 15ms the icon changes to a yellow exclamation mark, and when timed out a red error icon.
The code is working like it should(regarding the timed event), however the icon doesn't get replaced according to the timed response instead it adds a new icon every time
for example:
if the time is less that 15ms on first timed event:
Y
if the time is more than 15 ms on second timed event:
Y !
As you can see the Y remains whereas it should then just display the !
This is my code (aspx)
<asp:SqlDataSource ID="SqlDataSource1" runat="server"

For the code behind:
protected void UpdateTimer_Tick(object sender, EventArgs e)
{
Servers();
}
private void Servers()
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
Image Image3 = (Image)row.FindControl("Image3");
Image Image4 = (Image)row.FindControl("Image4");
Image Image5 = (Image)row.FindControl("Image5");
TimedPanel.Update();
string destIP = GridView1.DataKeys[row.RowIndex].Value.ToString();
{
try
{
Ping p = new Ping();
PingReply reply;
reply = p.Send(destIP);
if (reply.Status == IPStatus.Success)
{
if (reply.RoundtripTime > 15)
{
Image5.Visible = true;
Image5.ToolTip = Convert.ToString("RoundTripTime: " + reply.RoundtripTime + "ms");
}
else
Image3.Visible = true;
Image3.ToolTip = Convert.ToString("RoundTripTime: " + reply.RoundtripTime + "ms");
}
else
{
Image4.Visible = true;
Image4.ToolTip = reply.Status.ToString();
}
}
catch (PingException err)
{
Image4.ToolTip = err.Message.ToString();
Image4.Visible = true;
}
}
}
}
}
What I have tried was to update the panel by using:
TimedPanel.Update();
This didn't work though. Obviously when I refresh the entire page then it works but don't want to do that. I am also not sure if one can update just the column where the icons are being displayed after each timed event.
Any suggestions on how I get the icons to display one at a time after the timed event?
Thanks
Okay, I have resolved the issue.
Remove the Images from the ItemTemplate and add a panel
<ItemTemplate>
<asp:Panel runat="server" ID="Panel4"></asp:Panel>
</ItemTemplate>
Change the code behind to
Image Image2 = new Image();
Image Image3 = new Image();
Image Image4 = new Image();
Panel serverPanel = (Panel)row.FindControl("Panel4");
Add the images like this:
if (reply.Status == IPStatus.Success)
{
if (reply.RoundtripTime > 50)
{
Image2.ImageUrl = "../Images/yellow.png";
serverPanel.Controls.Add(Image2);
Image2.ToolTip = Convert.ToString("RoundTripTime: " + reply.RoundtripTime + "ms");
}
else
{
Image3.ImageUrl = "../Images/green.png";
serverPanel.Controls.Add(Image3);
Image3.ToolTip = Convert.ToString("RoundTripTime: " + reply.RoundtripTime + "ms");
}
}
else
{
Image4.ImageUrl = "../Images/red.png";
serverPanel.Controls.Add(Image4);
Image4.ToolTip = reply.Status.ToString();
}
}
catch (PingException err)
{
Image4.ImageUrl = "../Images/red.png";
serverPanel.Controls.Add(Image4);
Image4.ToolTip = err.Message.ToString();
}
so it will then be:
<asp:SqlDataSource ID="SqlDataSource4" runat="server"
ConnectionString="<%$ ConnectionStrings:constr %>"
SelectCommand="SELECT ip, host, device FROM [addfirewall]"></asp:SqlDataSource>
<asp:Timer runat="server" ID="UpdateTimer3" Interval="5000" OnTick="UpdateTimer3_Tick" />

I hope I was helpful.
Gridview update is not happening after I edit it. Used breakpoints and checked, its showing the same existing values which is there before editing. I am not getting any kind of error. Have used Store Procedure to update the Gridview. Please go through the code and help me sort out this problem.

GrdGetComments(); is running in your Page_Load, which binds the gridview again after editing (without saving). This needs to be in the (!IsPostBack).
Page life cycle indicates that Page_Load will always run before any other button clicks:
http://msdn.microsoft.com/en-us/library/ms178472(v=vs.90).aspx
You need to bind your gridview inside the if (!IsPostBack).
The stored procedure also needs a return value, for example adding a return to the end will allow you to grab this within your C# code.
so let say i want to create paging like "> 1 2 3 4 5 6 <" and i decided to use paging template in gridview and this is what i do :
aspx file :
<asp:GridView ID="gvDept" runat="server" CellPadding="4" ForeColor="Black"
GridLines="Horizontal" AutoGenerateColumns="False" BackColor="White"
BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"

DataSourceID="DS" DataKeyNames="departementcode" PageSize="3" OnRowCommand="gvDept_RowCommand">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox runat="server" ID="cbSelectAll" onclick="SelectAll(this)"></asp:CheckBox>
<%-- <asp:CheckBox runat="server" ID="cbAll" OnCheckedChanged="cbAll_CheckedChanged" AutoPostBack="true"></asp:CheckBox>--%>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox runat="server" ID="cbSelectOne"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateField>
<asp:HyperLinkField text="Edit" DataNavigateUrlFields="departementcode"
DataNavigateUrlFormatString="ManageDepartement.aspx?flag=edit&departementcode={0}" />
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete"
OnClientClick="return confirm ('Are you sure?');" Text="Delete">
</asp:LinkButton>
</ItemTemplate>
<ItemStyle ForeColor="Red" />
</asp:TemplateField>
<asp:BoundField DataField="departementcode" HeaderText="Departement Code" ReadOnly="True" SortExpression="departementcode" />
<asp:BoundField DataField="departementname" HeaderText="Departement Name" SortExpression="departementname" />
<asp:BoundField DataField="createby" HeaderText="Create By" SortExpression="createby" />
<asp:BoundField DataField="createdate" HeaderText="Create Date" SortExpression="createdate" />

<asp:BoundField DataField="lastupdate" HeaderText="Last Update" SortExpression="lastupdate" />
</Columns>
<FooterStyle BackColor="#CCCC99" ForeColor="Black"/>
<HeaderStyle BackColor="#333333" Font-Bold="True" ForeColor="White" />
<PagerSettings Mode="Numeric" />
<PagerStyle BackColor="White" ForeColor="Black" HorizontalAlign="Center" CssClass="paging"/>
<PagerTemplate>
</PagerTemplate>
<RowStyle BorderColor="White"/>
<SelectedRowStyle BackColor="#CC3333" Font-Bold="True" ForeColor="White" />

</asp:GridView>
<asp:LinqDataSource ID="DS" runat="server" ContextTypeName="Admin.AirAsiaDCDataContext"
EntityTypeName="" TableName="departements" EnableDelete="True" OnDeleted="DS_Deleted">
</asp:LinqDataSource>
and then i also put this code in C# :
protected void Page_Load(object sender, EventArgs e)
{
AirAsiaDCDataContext dc = new AirAsiaDCDataContext();
int dtcount = dc.departements.Count();
int pgcount = 0;
if (dtcount % 3 > 0)
{
pgcount = (dtcount / 3) + 1;
}
else
{
pgcount = pgcount / 3;
}
Button pagerBTN;
for (int i = 1; i <= pgcount; i++)
{
if(i == 1)
{
pagerBTN = new Button();
pagerBTN.ID = "btNext";
pagerBTN.Text = ">";
pagerBTN.CommandName = "Next";
gvDept.BottomPagerRow.Cells[0].Controls.Add(pagerBTN);
}
pagerBTN = new Button();
pagerBTN.ID = "bt" + i;
pagerBTN.Text = i.ToString();
pagerBTN.CommandName = i.ToString();
gvDept.BottomPagerRow.Cells[0].Controls.Add(pagerBTN);
if (i == pgcount)
{
pagerBTN = new Button();
pagerBTN.ID = "btLast";
pagerBTN.Text = "<";
pagerBTN.CommandName = "Last";
gvDept.BottomPagerRow.Cells[0].Controls.Add(pagerBTN);
}
}
}
protected void gvDept_RowCommand(object sender, GridViewCommandEventArgs e)
{
AirAsiaDCDataContext dc = new AirAsiaDCDataContext();
int datacount = dc.departements.Count();
int pagecount = 0;
int prevIDX = 0;
if (datacount % 3 > 0)
{
pagecount = (datacount / 3) + 1;
}
else
{
pagecount = datacount / 3;
}
if (e.CommandName == "Next")
{
if (gvDept.PageIndex < pagecount - 1)
{
prevIDX = gvDept.PageIndex;
gvDept.PageIndex = gvDept.PageIndex + 1;
if (prevIDX == pagecount - 2)
{
Button btn = (Button)gvDept.BottomPagerRow.Cells[0].FindControl("btNext");
btn.Visible = false;
}
}
}
else if (e.CommandName == "Prev")
{
if (gvDept.PageIndex > 0)
{
prevIDX = gvDept.PageIndex;
gvDept.PageIndex = gvDept.PageIndex - 1;
if (prevIDX == 1)
{
Button btn = (Button)gvDept.BottomPagerRow.Cells[0].FindControl("btPrev");
btn.Visible = false;
}
}
}
else
{
gvDept.PageIndex = Convert.ToInt32(e.CommandName) - 1;
}
}
my code working, but the problem is, if i click one of those paging button, after postback all my paging button which i generated before totally gone, i don't get it what i do wrong here? any correction?
In the grid view use
OnPageIndexChanging="gvDept_PageIndexChanging"
Add this code in .cs file to bind the data to grid view on each page index change.
protected void gvDept_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvDept.PageIndex = e.NewPageIndex;
// write here function to bind the grid to the datasource
}
Add this at the starting in Page_Load function so that the data gets bind to the grid view each time after postback.
if (!IsPostBack)
{
//function to bind the grid to data source
}
