I am currently highlighting a row in a radgrid using OnMouseOver. I would like to know if it is possible to use OnMouseOver to select the row rather than highlight it.
Alternatively, I would like the highlighted row to remain highlighted if the radgrid loses focus, such as when a confirmation box pops up.
I have icons in a gridview and when the user hovers over them the mouse pointer turns to hand and a tooltip is displayed. This works fine in IE 8. I'm testing in IE 9 and it doesn't work.
Code:
If e.Row.Cells(columnIndex).Controls(0).Visible Then
Dim iControl As System.Web.UI.WebControls.Image = e.Row.Cells(columnIndex).Controls(0)
iControl.Attributes.Add("onmouseover", "this.style.cursor='hand'")
End If
Displaying images on gridview is never been a problem to me but how can i enlarge my image onmouseover event in gridview?
View 2 Repliesi just made an onmouseover and onmouseout event using javascript and called the functions from the asp image tag like <contol.....onmouseover="thissss()" /> my question is why do i need to write javescrit for this? have heard so much praise of asp.net and c#! is there a way that is code to handle these events for all types of object using the .cs file (c#) directly?? i would assume the code will be under the page load event.
note:-
do not give answers assuming that the asker is a new bee consider him a completely un-educated person when it comes to coding )

But here it is in a nut shell.
I have a hyperlinks residing in a gridview some links are to files others to images. That gridview is set in a repeater.
What I'm looking to achieve is when the mouse hovers over a hyperlink that point to a jpeg, jpg or gif I would like to generate a thumbnail to show the user. when mouse leaves the hyperlink get rid of thumbnail.

I'm trying to use the onmouseover and the handler found above but no luck.
i am doing a web page in asp.net which holds logos of members in the page in a grid view.each cell is a link to the relevant member's website.
i want to popup an image of the member's website when the mouse is hovered over a certain cell. for this a snapshot of the website is stored in a database an for the onmouse over event i want to make it pop up.
i want to know whether using ajax or JavaScript is more appropriate for this problem.
i want to know how this can be done.
I am successfully using the well-documented Page_Load technique to apply onmouseover behavior to ImageButtons that behave as normal links or buttons. It works like this:
ImageButton2.Attributes.Add("onmouseover",
"src='Images/CreateAccountButtonHover.gif'");
ImageButton2.Attributes.Add("onmouseout",
"src='Images/CreateAccountButton.gif'");
PROBLEM: I have a Login control with Username, Password, and an ImageButton named "LoginButton" for the Login Button. I want to apply the same onmouseover behavior to the Login Button as I do other buttons on the page. When I try to use the same programmatic syntax as above, I get this error message:
The name 'Loginbutton' does not exist in the current context
Below is the declarative code.

I am currently learning dotnet (having recently learned ASP Classic) and i have come across the Menu Items and their ability to be based on the sitemap.
I love this idea and would like to use it on my demo site that i am building. However i cant seem to find a way to replace the links with images. I did have a look on google and noticed people wee using the ImageUrl method but said you have to code that yourself. I dont know how to tell it that imageUrl is ... well an image URL.
And then, should this be doable, is it possible to assign an onhover/onmouseover event to change the image?
I want to tuckle some issues about using javascript. I was using gridview control to display all my comments that are saved from the database. What I want is when the user hovers the mouse on each comment it will highlight the background which already solved and want to show one of the div element right there with close button and get the text value of one label control inside the <td> element during mouseover event. After getting the text value of that label during onmouseover I want to display it in another div element and I want to get the text value of another label control which is located outside the gridview during onmouseover event as well. Here are the details below:
HTML Layout:
<asp:Label ID="Label4" runat="server" Text=' <%#Eval("ID") %>'></asp:Label> //I want to get the text value of this control
<div id="test"></div> //here I want to put the text value of the name label control after getting it during onmouseover
<div id="Username" style =" margin-left :100px; width :1000px">
<asp:GridView ID="gvParentGrid" runat="server" Width="395px"
AutoGenerateColumns="false" GridLines="None" BorderStyle="Solid" BorderWidth="0px"
[CODE]...
Summary to tuckle some issues.
1. I need the Close div to show in every row of the gridview when hover because as of now using that code above would only show the Close div on the first row but if you move your mouse to another row the Close div row still remains showing on the first row which should supposed to transfer or show in another row when moving the mouse to another row.
2. I need to get the text value of the name label which is located inside the <td> element of the gridview and display it in div test during hover.
3. I need to get the text value of the Label4 which is located outside the gridview during onmouseover as well.
I have a gridview that when users click an asp:Button a confirmation box needs to appear. Inside that confirmation box, I want to include information from the gridview (DataKeyValues) that I can use in the codebehind to customize the confirmation message that pops up.
View 1 RepliesI am currently using Visual Studio 2008 to develop a hierarchical grid that displays records, its got 3 levels. The code looks roughly like this.
<telerik:RadMultiPage runat="server" ID="RadMultiPage1" SelectedIndex="0" RenderSelectedPageOnly="false">
<telerik:RadPageView ID="RadPageView1" runat="server">
<telerik:RadGrid ID="radGrd1">
<MasterTableView>

I have ommited all the code and just provided the skeleton.
The problem i am having is that when i add the Radgrid, the intellisense does not seem to pick it up and visual studio does not add it to the designer class either.
I have tried viewing it in design view and forcing it to sync and even manually added it to the designer class myself. These solutions have not solved my problem as although the intellisense does pick up the control after adding it manually, the control itself is set to null during run time.
So basically is it possible to add a rad grid in the first place and if so what am i doing wrong.
Is anyone able to offer any decent alternatives to the telerik ASP.Net controls.
I'm in the market for a decent grid control with all singing all dancing extensions... bt I'm finding the telerik grid really hard work to deal with.
The telerik controls do look good, but after a day of hard work with them I'm just looking to see if there are any other 3rd party offerings?
What's the simplest way to add a new row to a Telerik RadGrid in ASP.NET from code behind?
View 2 RepliesI'm using the Telerik rad grid and I'm allow the user to enter data directly to the grid.
I am using the "EditForms" edit mode and I also allow inserts using the same.
If the user edits a row, then I don't want to allow any other edits or inserts until the current one is complete or cancelled.
I created a RadGrid with a couple of fields for filtering and I can't seem to get the filtering to work. I can see it clearly posting back (the ajax spinny circle thing) after typing something in the filter box, however my results are always the same. I am using the following definition in the aspx file:
<telerik:RadGrid PageSize="4" ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" OnNeedDataSource="RadGrid1_NeedDataSource"
OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged" Skin="Black" ShowFooter="True"
ShowStatusBar="True" AllowFilteringByColumn="True"

All I want to do, is to get a values from a grid when it is not in edit mode. Note that I'm able to get two of the values (both the int32 fields), but I cannot get a reference to the "IsActive" Checkbox or the string "Delimiter" field.
let me know how I can accomplish this. Below is my code-behind. Notice the boldfaced fields I can't get...

give me any pointers for free tutorial on RADGRID or give me a simple example on how to create a RADGRID and bind it to data source.
View 2 RepliesI've tried to find the answer, but am not having any luck and am wasting to much time trying to figure it out. Using RadGrid from Telerik, latest version of their Ajax Controls, I've added a Select to each row, and can't figure out how to get the value of the selected row. Prefer to get the value of the ID column (from ID field in my database) or other specific columns. C# or VB example will work, VB preferred.
View 2 RepliesI have a Telerik RadGrid with a GridTemplateColumn that contains a checkbox, as follows:
<telerik:GridTemplateColumn HeaderText="MINE" UniqueName="MyTemplateColumn">
<ItemTemplate>
<asp:CheckBox id="MyCheckBox" runat="server"></asp:CheckBox>
</ItemTemplate>
</telerik:GridTemplateColumn>
I want to set the box to be "checked" based on a value read from the database. I could handle the ItemDataBound event and read the database when each row is bound, but that results in n lookups. Instead, I want to handle DataBound, and then set all the values at once. So, in that method, I want code like this:

I'm using RadGrid from Telerik with three LinkButton controls in CommandItem , and i want to hide or show them using switch statement at code behind.

I've a radgrid and rendering a hyperlink column. I want to pass the id of the record into the url for the hyperlink. How can I do this?

There is an ID column which is generated too.
I want to take an already existing row in a RadGrid and instead of open an edit template I want to open the Insert template with that data.
I have a requirement to allow the user to make edits to the rows on their "key" values, the result being a new row that they didnt have to type everything over again.
My guess is to put an insert button on the row, but I'm not sure how to open the insert template and still have it bind that rows data to it.
using Telerik RadGrid* in a LINQ context, with ASP.NET/C#, how to truncate text to a maximum length when displaying in columns? By maximum, I mean if original string's length is shorter than the specified maximum length, no errors will raise.I have seen many examples of this on the net, but it seems that the Container.DataItem used to achieve this is different when using LINQ. Sometimes we see DataItem as a method, sometimes not. Examples are usually using a DataSet.Here's an example found (source) :
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<%# ValidateString(Container.DataItem("Description")) %>
