I have a logLink column in my database.
I have my hyperlink field in gridView as below :
<asp:HyperLinkField DataNavigateUrlFields="logLink" DataTextField="logLink" DataNavigateUrlFormatString="{0}" Text="Link" ControlStyle-CssClass="hlink" HeaderText="LOG LINK" ItemStyle-Width="6%" ItemStyle-Font-Underline="true" />
But this link is not clickable.
I want the values in the log link column of my db to come here.
Does anyone know how to solve this ?
try this.
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="lnk" runat="server" Target="_blank" Text='<%# Eval("yourText") %>'
NavigateUrl='<%# Eval("logLink") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>

I am importing a column in datatable to my grid. Now I want navigate to a new page on selecting a cell in grid by fetching the selected value. I have tried this by including bound field in my grid like
<asp:GridView ID="GDV_1" runat="server" EnableModelValidation="true" AutoGenerateColumns="false" OnSelectedIndexChanged="GDV_1_SelectedIndexChanged" AutoGenerateSelectButton="false" DataKeyNames="SROID">
<Columns>
<asp:BoundField DataField="SRONameinEnglish" HtmlEncode="False" DataFormatString="<a target='_blank' href='Test.aspx?code={0}>ClickHere</a>" />
</Columns>
</asp:GridView>
Doing this way my requirement is achieved but the all cells are displaying Common text Click here instead of showing data from Database.
Please give your suggestion on how to get the value from database into cell and make it clickable. I don't want to use Select button. Please find my current output.
This is my current output I want my data from DB instead of ClickHere.
You can use TemplateField
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:LinkButton runat="server" ID="lnk<%# Eval("SRONameinEnglish")%>"><%# Eval("SRONameinEnglish")%></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
and click of LinkButton put your code to navigate anywhere.
In your case you are binding boundfield with static a tag which have href attribute so your not able to change text on that boundfield from your database.To get your approach you should
use TemplateField and bind data with text attribute using eval keyword as below example.
Try it:
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("name") %>' />
</ItemTemplate>
</asp:TemplateField>
OR
you can also bind link with your hyperlink using NavigateUrl property of hyperlink as below example.
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:HyperLink id="HyperLink2" NavigateUrl='<%#Eval("YourUrl") %>' Text='<%#Eval("name") %>' runat="server"/>
</ItemTemplate>
</asp:TemplateField>
I hope it will helpful to you.
<telerik:GridTemplateColumn HeaderText="Code" SortExpression="Code" UniqueName="Code" AllowFiltering="True">
<ItemTemplate>
<asp:LinkButton ID="lbCCode" runat="server" Text='<%# Eval("Code") %>' />
</ItemTemplate>
</telerik:GridTemplateColumn>
So how can I allow RadGrid to filter the results based on the text value of LinkButton? Is there a way to do that?
Please try with the below code snippet.
<telerik:GridTemplateColumn HeaderText="Code" SortExpression="Code" UniqueName="Code" AllowFiltering="True"
DataField="Code">
<ItemTemplate>
<asp:LinkButton ID="lbCCode" runat="server" Text='<%# Eval("Code") %>' />
</ItemTemplate>
</telerik:GridTemplateColumn>
I have added DataField property in template column. if you get any error in grid then please set EnableLinqExpressions="false" in your grid.
I have a gridview with a hyperlink:
<asp:GridView ID="gvEmployees" runat="server" AutoGenerateColumns="False"
CssClass="table table-hover table-striped" GridLines="None" >
<Columns>
<asp:TemplateField HeaderText="Name" SortExpression="EmployeName">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
Text='<%# Bind("EmployeName") %>' ></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ID" SortExpression="EmployeID" Visible="False">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Bind("EmployeID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
However, it should only appear as a hyperlink if the employeeID is that of the logged in employee.
I can do all that, but what I do not know is how to make the hyperlink look like a Label. It's easy to have it not link anywhere, but I do not know how to make it look like a label.
Thanks
I believe if you set Enabled="false" it does. If it does not, then the only way to do that is put both a HyperLink and Label in the cell, and show the link when appropriate, and the label when appropriate, hiding the other one (which can be easily done in RowDataBound event).
I want to get the value of a hidden field in a grid view from code-behind, but not to be used in the _RowDataBound or any other similar method. Here is my present code (it is a shopping cart scenario):
<asp:GridView ID="gvShoppingCart"
runat="server"
AutoGenerateColumns="False"
AllowPaging="True"
DataKeyNames="ID"
ShowFooter="true">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="lblProductID" runat="server" Text='<%# Eval("ProductID") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Product">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# Eval("ProductID", "product_details.aspx?id={0}") %>'
Text='<%# GetProduct(Eval("ProductID")) %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox ID="txtQuantity" runat="server" Width="35" CssClass="input" onkeypress="return isNumberKey(event)" AutoPostBack="true" ontextchanged="txtQuantity_TextChanged"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
For the sake of brevity I removed certain fields since they are there only for the display. The Quantity field is there for the user to input a number to add a number of products to his cart. I wish to access the lblProductID label in the _TextChanged event. In this same event, I tried
Label lblProductID = (Label)gvShoppingCart.FindControl("lblProductID");
but it didn't work and returns only a null value. What is the solution?
For each row in your GridView there is a HiddenField for the ProductID.
You can access the HiddenField of a row (in the example below the first row) by using the following code (assuming your HiddenField is in the first cell):
HiddenField hiddenFieldProductID =
(HiddenField)gvShoppingCart.Rows[0].Cells[0].FindControl("lblProductID");
string productID = hiddenFieldProductID.Value
// Do something with the value
Hope, this helps.
Try to replace the HiddenField to a label or a textbox and set the visible attribute to false.
I had tried this before and it works.
I have a bound field in my Gridview which is getting its value from a database table.
I have got the data but don't know how to format it inside the gridview.
For example I get total data from below like "123456", but I want to display as "123,456"
<asp:BoundField DataField="totaldata" HeaderText="Total Data"
ReadOnly="True" SortExpression="totaldata" />
How can I do this? Do I need to convert the bound field into a template field ? But what do i do after that.
please help.
I have used DataFormatString="{0:n0}" and it solved the above problem.
how do i do for this:
<asp:TemplateField HeaderText="Failed Files"
SortExpression="NumFailed">
<ItemTemplate>
<asp:Image ID="Image2" runat="server" ImageUrl="~/NewFolder1/warning_16x16.gif" />
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
the hyperlink has the number which need to be formatted...
Use DataFormat property :
<asp:BoundField DataField="totaldata" HeaderText="Total Data"
ReadOnly="True" SortExpression="totaldata" DataFormatString="{0:n3}" />
EDIT : For the second part of your question use Eval method's second parameter to format your data :
<%# Eval("NumFailedFiles", "{0:n3}") %>
Then your template will be like that :
<asp:TemplateField HeaderText="Failed Files"
SortExpression="NumFailed">
<ItemTemplate>
<asp:Image ID="Image2" runat="server"
ImageUrl="~/NewFolder1/warning_16x16.gif" />
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>'
Text='<%# Eval("NumFailedFiles", "{0:n3}") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
A couple of ways in how you can do that
Option 1
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx?id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles","{0:n0}") %>'></asp:HyperLink>
Option 2
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx? id="+Eval("MachineID") %>' Text='<%# Bind("NumFailedFiles").ToString("N") %>'></asp:HyperLink>
Option 3
Create a method in the code behind page that returns the formatted number.
protected string GetFormatedNumber(object number)
{
if ( number != null )
{
return number.ToString("N");
}
return "0";
}
And call the method in your aspx page as below:
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "GetFilesFailed.aspx? id="+Eval("MachineID") %>' Text='<%#GetFormatedNumber(Eval("NumFailedFiles")) %>'></asp:HyperLink>
I think you need to take a look at this MSDN article on How to Format Data in the DataGridView
if you want to format your data on gridview use "{0:n3}"
<asp:Label ID="label" runat="server" Visible="true" Text='<%#DataBinder.Eval(Container.DataItem, "data","{0:n3}") %>'></asp:Label>
