How To Change The Visibility Of A Hyperlinkfield In A Gridview
Jan 27, 2010
I have a gridview with some data and two hyperlinkfields.I want to make the first hyperlinkfield of the first row not visible and the second hyperlinkfield of the last row not visible.this what I did till now
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code]....
This will work only for the first hyperlinkfield.Omitting the comments will make the first hyperlinkfield not visible for all rows.
I want to change controls visibility on c#, but nothing happens. The controls are in an AspxPopupControl and 3 of them are hidden in design time, 1 of them is visible. I use this code to visible them
aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.
I have a webform containing a user control. On that user control is a set of radio buttons. When the radio button is changed, a panel and a text box is shown or hidden depending on which radio button was selected.I can give you an example that works correctly:testcontrol.aspx:
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
I have Table named PRODUCTS , that have 4 column productid, productprice,productname & discount( type numeric(18,0)) .. i am using datalist with itemtemplate that have 4 label to display all ..
I am binding datalist on pageload, now i want that Label4 with "discount" should only visible for those product that have discount , otherwise it remains hidden,
Problem in my code is that when i run it , label becomes invisible for all products whether they have discount or not. Here is my code i am using for it:
ds1 is my dataset
foreach (DataListItem item in DataList1.Items) { for (int i = 0; i <= ds1.Rows.Count - 1; i++) { double[] arr = new double[ds1.Rows.Count]; double temp = double.Parse(ds1.Rows[i]["discount"].ToString()); arr[i] = temp; Label lbl = item.FindControl("Label4") as Label; if (arr[i] == 0) lbl.Visible=false; } }
How to change visibilty of panel based on imagebutton mouseover and mouseout here, i have panel1(Panel) and btnimg2(imagebutton) i want to show(Panel1.visibility=true) when mouseover happens on imagebutton and Panel1.visibility=false when mouseout on imagebutton
I have a details view with buttons in the footer. When the user clicks the edit button the calls the ChangeEditMode() method. I want to change the mode of the details view to edit mode which seems to work fine. It goes into edit mode with a text box. I also want it to set the visible property of the edit button to false and set the visible property of the update button to true. Then while still in edit mode the user can click the update button that will call the appropriate method to persist the changes.
I got the changemode() to change to edit but can't change the visible property of the buttons correctly. This is what I have so far. Can some one please tell me what I'm doing wrong?
I'm trying to get the text of a HyperLinkField in a GridView's OnRowDelete event (the HyperLinkField's text is the primary key of the row I wish to delete). I understand that you can't get the text using the code I've placed below; it only works for BoundFields (for HyperLinkFields, the string is ""). But, I've been unable to find a working answer for getting this text. How do I get the displayed text from a HyperLinkField? (VS2010 w/ ASP.NET 4.0 and C#)
I have a gridfield which is being populated and in one of my cells the first there are hyperlinkfields. to get the rownumber of the hyperlinkfield just like it is with a buttonfield. Unfortunately I cannot use a buttonfield else my problem would have been solved. I cannot find an event associated with the hyperlinkfield and it is also not doing any postbacks if I recall the info correctly. If this is possible how do I achieve this ?
as requested the edit:Protected Sub objGridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
Dim strProID As String If e.CommandName = "Select" Then Dim index As Integer = Convert.ToInt32(e.CommandArgument) [code]...
This was my code when i used a linkbutton. The linkbutton from the gridview has an attribute commandname and you can use this so your event will be raised. Which I did. Unfortunately for the hyperlinkview cell does not have such a property. So I can't raise an event and see which rownumber i selected if I click on one of my with hyperlinkfilled cells.
edit.So I fixed my problem with just a simple DataNavigateFormatString.I know foolish of me to not get there sooner, but better late then never. Why mess around with the rownumber to get the value from my cell, if I can get the value much cleaner , quicker and without postbacks;).
I am stumped on this one. I want to modify the text in a Hyperlinkfield of Gridview after the data is bound to it. I found similar code to this on msdn and I can't get it to work.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[2].Text = e.Row.Cells[2].Text + "random text"; } I also tried similar code in the Page_PreRender event with no luck. I have also tried calling DataBind() before this one line of code with no help. I always just get "random text" in the cell without the data from the DB.
I'm having a problem passing a date value from a GridView generated hyper link field to another page. Through some searching, I believe I'm using the correct syntax to generate the link, but whenever I try to bind a date to the DataNavigateUrlFields property, it won't create the hyper link. As I understand GridView, it won't generate the hyper link if the url is bad.
The method I'm using method does work when passing other fields; it only seems to be choking on the date value. This is the code I'm using, can anyone see what I might be doing wrong?
I have an existing GridView which contains the field "partner name". It is sortable by partner name.Now I need to change the Partner Name field and in some condition make it clickable and alert() something.
I have a hyperlinkfield in Gridview control. I am using the below shown stylesheet for the gridview.But for some reason, the hyperlinkField column in the gridview is not in blue color and there is no underline.How can I display the hyperlinks as regular hyperlinks as blue in color and underline?
here i am passing session id, to another page there capturing id to display some content. But i am getting error as "Object reference not set to an instance of an object." while capturing id in redirected page.
