Everything seems to be fine with my GridView and code behind, but event does not fire.
Here is my Grid:
<asp:UpdatePanel ID="ISOSearchUpdatePanel" runat="server">
<ContentTemplate>
<div id="divIsoSelect" style="width:700px; height:60px; background-color:white">
<fieldset>
<legend style="font-size: larger; font-weight: bold">Search ISO by</legend>
<table>
<tr>
<td><asp:DropDownList ID="ddlISOSearch" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlISOSearch_SelectedIndexChanged">
<asp:ListItem Value="">Select...</asp:ListItem>
<asp:ListItem Value="ISO Number" >ISO Number</asp:ListItem>
<asp:ListItem Value="Name">Name</asp:ListItem>
<asp:ListItem Value="Region" >Region</asp:ListItem>
<asp:ListItem Value="Division">Division</asp:ListItem>
</asp:DropDownList></td>
<td > </td>
<td>
<asp:Panel ID="pnlSearchEntry" runat="server" Visible="false" style="width:500px; border:gainsboro; border-width: thick;">
<table>
<tr>
<td valign="middle" style="width:120px"><asp:Label ID="lblEntry" runat="server" Text=""></asp:Label></td>
<td valign="top"><asp:TextBox ID="txtSearchValue" runat="server"> </asp:TextBox></td>
<td valign="top"> <asp:Button ID="btnFind" runat="server" Text="Select" OnClick="btnFind_Click"/></td>
</tr>
</table>
</asp:Panel>
</td>
</tr>
</table>
</fieldset>
</div>
<asp:GridView ID="grvIsoSearchResults" runat="server"
AutoGenerateColumns="false" PageSize="15"
AllowPaging = "true" Visible="false" BorderColor="Red" GridLines="Both"
OnRowCommand="grvIsoSearchResults_RowCommand"
DataKeyNames="isonum"
OnPageIndexChanged="grvIsoSearchResults_PageIndexChanged"
OnPageIndexChanging="grvIsoSearchResults_PageIndexChanging"
OnSorting="grvIsoSearchResults_Sorting"
style="position:absolute; top: 120px;">
<PagerSettings firstpagetext="First" lastpagetext="Last" nextpagetext="Next" pagebuttoncount="100" />
<Columns>
<asp:TemplateField HeaderText="ISONUM" SortExpression="isonum">
<ItemTemplate>
<asp:Label ID="txtgvIsoNum" Text = '<%# Eval("ISONUM")%>' runat="server" Width="70px" style="text-align:center" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="OFFICE NAME" SortExpression="isoofficename">
<ItemTemplate>
<asp:Label ID="txtgvIsoOfficeName" Text = '<%# Eval("ISOOFFICENAME")%>' runat="server" Width="200px" style="text-align:center" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="REGION" SortExpression="region">
<ItemTemplate>
<asp:Label ID="txtgvRegion" Text = '<%# Eval("REGION")%>' runat="server" Width="50px" style="text-align:center" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="DIVISION" SortExpression="client_id">
<ItemTemplate>
<asp:Label ID="txtgvDivision" Text = '<%# Eval("CLIENT_ID")%>' runat="server" Width="50px" style="text-align:center" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="EMAIL ADDRESS">
<ItemTemplate>
<asp:TextBox ID="txtgvEmailAddress" Text = '<%# Eval("EMAIL")%>' runat="server" Width="200px" />
<asp:Button ID="btnEmailUpdate" Text = "Update" runat="server" CommandName="UpdateEmail" onClientClick="return ValidateEmail(this)" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<pagerstyle backcolor="#005482" ForeColor="White" height="30px" verticalalign="Bottom" horizontalalign="Center"/>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
And this is my code-behind methods:
private void SetViewState(DataSet myDataSet)
{
ViewState["Data"] = myDataSet;
}
private DataSet GetViewState()
{
return (DataSet)ViewState["Data"];
}
private void LoadData(String selection, String userInput)
{
DataSet ds = new DataSet();
.
.
.
ds = ISOProcessing.GetISOData(selection, userInput);
grvIsoSearchResults.DataSource = ds;
if (ds.Tables[0].Rows.Count > 0)
{
SetViewState(ds);
grvIsoSearchResults.DataBind();
grvIsoSearchResults.Visible = true;
}
else
{
lblMsg.ForeColor = System.Drawing.Color.Red;
this.lblMsg.Text = "No data for current selection";
}
}
protected void grvIsoSearchResults_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
grvIsoSearchResults.PageIndex = e.NewPageIndex;
grvIsoSearchResults.DataSource = GetViewState();
grvIsoSearchResults.DataBind();
}
Everything seems to be in place, but when I want to go to another page during debugging, break point is not even hit inside of my grvIsoSearchResults_PageIndexChanging() method. I'm not sure why that happens.
Need your help.
Thank you
Try to add a trigger for it:
