I am using Data Repeater and Link Button inside repeater . I want to change the color of clicked button but it is not working . Here is my code.
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<asp:LinkButton Font-Size="Larger" BackColor="Orange" ForeColor="White" ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
CssClass=" btn"
OnClick="Page_Changed"></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
protected void Page_Changed(object sender, EventArgs e)
{
int pageIndex = int.Parse((sender as LinkButton).CommandArgument);
LinkButton lnk = (LinkButton)sender;
lnk.ForeColor = System.Drawing.Color.Red;
lnk.BackColor = System.Drawing.Color.Red;
this.GetImagesPageWise(pageIndex);
}
Do this way. Create class for Current Page LinkButton
.Active
{
color:red;
font:bold 12px Tahoma;
}
Then Change the Repeater as following
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
Enabled='<%# Eval("Enabled") %>' OnClick="Page_Changed" CssClass='<%# Convert.ToBoolean(Eval("Enabled")) == true ? "LBR" : "Active" %>'></asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
<ul class="pagination">
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<li class="<%#GetStatus(Eval("Enabled").ToString(),Eval("Text").ToString())%>">
<asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
Enabled='<%# Eval("Enabled") %>' OnClick="Page_Changed">
</asp:LinkButton>
</li>
</ItemTemplate>
</asp:Repeater>
</ul>
Protected Function GetStatus(ByVal Enable As Boolean, ByVal linkName As String) As String
Try
If Enable = 0 And linkName <> "First" And linkName <> "Last" Then
Return "active"
Else
Return ""
End If
Catch ex As Exception
Return ""
End Try
End Function

I used pagination as described in this article
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
CssClass='<%# Convert.ToBoolean(Eval("Enabled")) ? "page_enabled" : "page_disabled" %>'
OnClick="Page_Changed" OnClientClick='<%# !Convert.ToBoolean(Eval("Enabled")) ? "return false;" : "" %>'></asp:LinkButton>
</ItemTemplate></asp:Repeater>
This is link to Demo
I want to customize the pagination style by using bootstrap 4 pagination class
This is what i did but the current page is not highlighted
<ul class="pagination"> <asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<li class="page-item">
<asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
CssClass="page-link"
OnClick="Page_Changed" OnClientClick='<%# !Convert.ToBoolean(Eval("Enabled")) ? "return false;" : "" %>'></asp:LinkButton>
</li>
</ItemTemplate>
</asp:Repeater></ul>
How can i use BOTH CssClass="page-link" AND CssClass='<%# Convert.ToBoolean(Eval("Enabled")) ? "active" : "disabled" %>'
You can combine more classes by separating them by space. Example below.
<ul class="pagination">
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
<asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
CssClass='<%# Convert.ToBoolean(Eval("Enabled")) ? "active page-link" : "disabled page-link" %>'
OnClick="Page_Changed" OnClientClick='<%# !Convert.ToBoolean(Eval("Enabled")) ? "return false;" : "" %>'>
</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
</ul>
I am building a website right now using DataLists and I want to ask a question:
When using OnLoad on specific control in DataList item, the DataList has 5 items, but the function is called only 4 times (does what it needs to do but not on the last item)
C# code:
protected void ibDeleteAlbum_Load(object sender, EventArgs e)
{
foreach (DataListItem item in DataList1.Items)
{
ImageButton btnDelAlbum = item.FindControl("ibDeleteAlbum") as ImageButton;
btnDelAlbum.Visible = true;
}
}
HTML code:
<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal" RepeatColumns="4" >
<ItemTemplate>
<asp:Label ID="lblAlbumID" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Id") %>' Visible="false"></asp:Label>
<asp:ImageButton ID="ibDeleteAlbum" type="image" runat="server" style="position:absolute; margin-right: 1.4vw; margin-top: 2.4vh;" Visible="false" ImageUrl="~/Images/ic_delete.png" OnClick="ibDeleteAlbum_Click" ToolTip="מחיקה" OnLoad="ibDeleteAlbum_Load" />
<asp:ImageButton ID="ibShowAlbums"
runat="server"
class="album"
ImageUrl='<%# DataBinder.Eval(Container.DataItem, "coverPhoto") %>'
CommandName="album"
CommandArgument='<%#DataBinder.Eval(Container.DataItem, "ID") %>'
OnCommand="ibShowAlbums_Command" />
<div class="albumNameShow" runat="server"><%#DataBinder.Eval(Container.DataItem, "albumName") %></div>
</ItemTemplate>
</asp:DataList>
Thanks ahead!
I am facing a kind of weird problem.
Problem:
When I click a link button inside a grid view then RowCommand event of a grid view is getting fired when deployed on a localhost but not when deployed on the IIS i.e. client system. I have also tried a link button inside grid view but that's also not getting fired.
Solution: (Temporary)
When I disabled ValidateRequest on the top of the .aspx page. It worked.
What should I do?
So what can be the possible solution for it? I have googled but nothing good came up.
Code:

It sounds like your page is trying to submit what it thinks is potentially dangerous content if setting the ValidateRequest = false solves the issue. Is it possible that one of the controls on your page is sending html or something like that?
If one of your controls needs to send HTML then you can overcome this by adding an attribute to your model.
[AllowHtml]
[Required]
public string article_content { get; set; }
This will allow html to be entered into the control.
I get this error on this column in a `gridview' :-
<asp:TemplateField>
<ItemTemplate>
<%# Eval("title") %>
<br />
<p runat="server" id="description"><%# Eval("des") %></p>
<asp:ImageButton ID="click_like" runat="server" ImageUrl= "~/pics/like.png" Height="20px" CommandName="like" CommandArgument='<%# Eval("id") %>' BorderStyle="Outset" BorderColor="#99CCFF" Enabled='<%# Eval("like_enabled") %>' />
<asp:Label ID="lbl_like" runat="server" Text='<%# Eval("like") %>'></asp:Label>
<asp:ImageButton ID="click_dislike" runat="server" ImageUrl="~/pics/dislike.png" Height="20px" CommandName="dislike" CommandArgument='<%# Eval("id") %>' BorderStyle="Outset" BorderColor="#99CCFF" Enabled='<%# Eval("dislike_enabled") %>'/>
<asp:Label ID="lbl_dislike" runat="server" Text='<%# Eval("dislike") %>'></asp:Label>
<p runat="server" id="labels"><%# Eval("labels") %></p>
</ItemTemplate>
</asp:TemplateField>
I get this error on the line:-
<asp:ImageButton ID="click_like" runat="server" ImageUrl= "~/pics/like.png" Height="20px" CommandName="like" CommandArgument='<%# Eval("id") %>' BorderStyle="Outset" BorderColor="#99CCFF" Enabled='<%# Eval("like_enabled") %>' />
And I get this because I am binding the value of Enabled attribute from a DataTable where like_enabled column is either "true" or "false"
You're not able to bind Enabled like that, you'll have to use an RowDataBound event:
<asp:GridView id="myGrid" OnRowDataBound="myGrid_RowDatabound">
Code behind:
public void myGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
var enabled = (bool)DataBinder.Eval(e.Row.DataItem, "like_enabled");
var click_like = e.Row.FindControl("click_like") as ImageButton;
click_like.Enabled = enabled;
}
}
I have a DataList inside another DataList. I want to access the child DataList "dlQuestion" events, ItemDataBound event. Also, I'm tring to find the control LableControl "lblQuestion" in the child datalist. How do I do that? Here's the mark-up:
<asp:DataList ID="dlSection" runat="server" Width="100%">
<ItemTemplate>
<div>
<asp:Label ID="lblSection" runat="server" Text='<%# Eval("Section") %>'></asp:Label>
<asp:HiddenField ID="hfSectionId" runat="server" Value='<%# Eval("SectionId") %>' />
</div>
<asp:DataList ID="dlQuestion" runat="server" >
<ItemTemplate>
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Question") %>'></asp:Label></td>
<asp:HiddenField ID="hfQuestionId" runat="server" Value='<%# Eval("QuestionId") %>' />
</ItemTemplate>
</asp:DataList>
</ItemTemplate>
</asp:DataList>
You need to handle ItemDataBound event of the dlQuestion DataList and get lblQuestion Label in that event handler:
Markup:
<asp:DataList ID="dlSection" runat="server" Width="100%">
<ItemTemplate>
<div>
<asp:Label ID="lblSection" runat="server" Text='<%# Eval("Section") %>'></asp:Label>
<asp:HiddenField ID="hfSectionId" runat="server" Value='<%# Eval("SectionId") %>' />
</div>
<asp:DataList ID="dlQuestion" runat="server" OnItemDataBound="dlQuestion_ItemDataBound">
<ItemTemplate>
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Question") %>'></asp:Label></td>
<asp:HiddenField ID="hfQuestionId" runat="server" Value='<%# Eval("QuestionId") %>' />
</ItemTemplate>
</asp:DataList>
</ItemTemplate>
</asp:DataList>
Code-behind:
protected void dlQuestion_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
var lblQuestion = e.Item.FindControl("lblQuestion") as Label;
if (lblQuestion != null)
{
lblQuestion.ForeColor = Color.Red;
}
}
}
This is one way finding label control in child datalist...
//here I am finding item(DataList) of child Datalist
DataList dlSubChild = (DataList)childItem.FindControl("dlSubChild");
foreach (DataListItem subChildItem in dlSubChild.Items)
{
//here I am finding item(TextBox) of sub child Datalist
TextBox txtName = (TextBox)subChildItem.FindControl("txtName");
//set literal(litName) text
litName.Text = string.Format("{0}{1}", "Welcome ", txtName.Text);
}
i hope it will helps you ...
