I am new to C# and I have a LinkButton inside a gridview. I have been trying to set the myLinkButton.Visible property true or false depending on a database entry.Here is the code behind I have been working on:
protected void gvBalance_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)

I'm trying to change the visibility of a imagebutton to false, if the imagebutton.ImageUrl="". The problem is that the imagebutton is inside "ListView2", and "ListView2" is inside "ListView1". Who can I do this in vb code... or even a javascript.
View 4 RepliesI have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+"IsAdmin"(within the UserDetail table)
What I need is that by clicking this "delete_linkButton",it will ONLY delete the entire User Entity on the same row (link by the corresponding "UserName") from the "UserDetail" table,as well as delete all information from the AspNetDB.mdf (User,Membership,UserInRole,etc). I would like to fireup a user confirm,but not mandatory. At least I am trying to make it functional in the correct way.
[Code]....
When I click "delete" on the first row, I need all the record about "ken" inside the "UserDetail" table to be removed. Meanwhile, all the record about "ken" in the AspNetDB.mdf will be gone, including UserinRole table. I am new to asp.net, so I don't know how to pass the commandargument of the "Delete_LinkButton" to the code-behind file LinkButton1_Click(object sender, EventArgs e), because I need one extra parameter "UserName". My partial code is listed below:

I am requested by my manager to develop a web page called staff deployment plan that will involve two GridViews, that is the Parent GridView and Child GridView. The Parent GridView will display two columns which are EmployeeNames and WorkingDays - the working days column is a heading of Child GridView and the child gridview displays columns as current working days for example: the month of November 2014 has 20 working days excluding weekends and public holidays in South Africa, so the columns for child gridview are like this:
3 Nov, 4 Nov, 6 Nov...etc
The problem that am experiencing now:
Is to add LinkButton for each column on the Child GridView and to create command event for each linkbutton inside a child gridview (remember this child gridview is inside a parent gridview) and the link button when is click it should display a popup window.
I have a linkbutton in a detailsview and there is a provision to update and add new records. WHen I click the "linkbutton" a textbox appears and users can add something.
I have a grid as well from which I can select a record to update and the update button which is inside the details view lets update. But the "linkbutton" won't function when I hit any any controls inside the grid.
Basically, the detailsview's mode is changed to edit. But clicking the cancel button does not come back to the original state. What should I do?
i have added a hyperlink in the gridview and i am displaying the image names in the grid as hyperlinks
when i click on the hyperlink in the grid, the related image has to be displayed in the same page but in another div which is next to gridview
but for me ,image is displaying in another page
I have Repeater, which consists of LinkButon and Literal. LinkButon and Literal are whole thing by implication. I want get value from Literal, when user click on corresponding LinkButton.
View 3 RepliesI have an ItemTemplate inside a listview with a linkbutton wrapped around three table rows. The linkbutton is supposed to make the whole rows clickable but this only works in IE. Does anyone have an idea about why? The link works if I move the rows out of the linkbutton and write some gibberish text instead, but that's not what I want.

How can I make a linkbutton inside a repeater open a new browser window on click?

I have a LinkButton that is databound to a description. Sometimes the descriptions are very long and unorganized so I would like it to show for example 75 characters and then append a '...' to the end of any description greater than 75 characters. I found this snippet which pretty much is exactly what I want to do :

I just cant figure out how to do this for the LinkButton in my ItemTemplate in the DataList.
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
[Code]....
and im not getting the result i expected =
I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.
I have two page
1-index.aspx
protected void ImageButton3_Click(object sender, ImageClickEventArgs e) {
string data = Server.UrlEncode(txtNumeric.Text);
SqlCommand _cmd = new SqlCommand("traidname", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cmd.Parameters.Add("@BehCode", data);
[Code] ....
Here I use textbox .text for server.urlEncode according to this code it go to tName + "?BehCode=" thatÂ
SP
ALTER procedure [dbo].[traidname]
@Behcode nvarchar(30)
as
begin
select T_name
from House_Info
where Behcode=@Behcode
end
And this is code in my destination(depending to tname column in house_info tabel) page
I use below code to bind data from database in destination pages
 string data = Server.UrlDecode(Request.QueryString["BehCode"]); _cmd.Parameters.AddWithValue("@behcode", data);
Now in index.aspx page i have linkbutton that i want when users click on it, it do something like
ImageButton3_Click  eventÂ
This is my datalist code that linkbutton is in this datalist
 <asp:DataList ID="DDLstore" runat="server" RepeatColumns="3" RepeatDirection="Horizontal" "> <ItemTemplate> <table class="DDL2h"> <tr> <td style="height: 35px"> <asp:Label ID="Label3" runat="server" Text='<%# Eval("Name") %>' CssClass="TDnameH"></asp:Label> </td> <tr> <td> <asp:LinkButton ID="LinkButton2" runat="server" CssClass="LBP2" onclick="LinkButton2_Click">see all product</asp:LinkButton> </td> </tr> </table> </ItemTemplate> </asp:DataList>
Now how I can write code for linkbutton event that do same thing like ImageButton3_Click event?
and notice that both linkbutton and imagebutton are in index.aspx page ...
I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

I am using an event calendar control (not a MS control) and I am trying to access a LinkButton inside this control's HeaderTemplate. Below is what I have tried so far. I get the familiar "Object reference not set to an instance of an object" error. Does anyone has an alternate way to get this control? I need to change the visibility property of it.
<ec:EventCalendar runat="server" ID="eventscalendar"...
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
<tr>
<td style="text-align: left; width: 33%; font-weight: bold; font-size: small; color: blue">
«
<asp:LinkButton ID="PrevMonth" runat="server" Text='Previous Month' CommandName="PrevMonth" />
</td>
...
</HeaderTemplate>
LinkButton PrevMonth = (LinkButton)form1!eventscalendar.FindControl("PrevMonth") as LinkButton;
LinkButton PrevMonth = this.FindControl("form1!eventscalendar!HeaderTemplate!PrevMonth") as LinkButton;
Can i put gridview inside gridview and bind data to that inside grid?

I am trying to add a LinkButton in a GridView that when clicked activates the the AJAX ModalPopupExtender to allow the User to Confirm if they want to Delete a Row.f they click Yes the Delete method should then take place.

I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both traditional event handler ("OnClick")A OnRowCommand event handler at the GridView level.In both cases, I've debugged and it doesn't even catch the event handler.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Cancel" ID="DeleteButton" CausesValidation="false" OnClick="CancelThis" runat="server" />

How do I add a LinkButton to a GridView pager? The only way I can think of implementing this is to dynamically add the numeric pages in the code behind and add the LinkButton I require in the PagerTemplate. owever in the example illustrated when a user clicks a numeric Page number the numbers disappear and nothing fires. My GridView is in an UpdatePanel.
