Forms Data Controls :: Passing Grid As A Property To User Control?
Aug 10, 2010
In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.
I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.
Code behind:
[Code]....
ASPX:
[Code]....
That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.
Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
This is driving me nutty... I have a gridview on a page. On the same page is a web user control with several public properties. Using the gridview's selectedindexchanging event, I try to set the user control property, but it's always null. Like this: protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e) { usercontrol1.ID = grdPhysicians.SelectedValue.ToString(); [code]....
If I write the grdPhysicians.SelectedValue to the page, I can see it's there. It just won't pass to the web user control.What I'm trying to do is have a master record form with child records in a web user control and just pass the selected record id into it.
I am dynamically loading user controls into my main page on button event.The user control has a textbox and a gridview When i enter data in textbox , the autopostback event fires and loads data into the gridview. when i load another instance of user control and do any post back the gridview data is not persisting.Until and unless I bind the data, gridview is not having any data after postback.This is creating issue when I al updating a row in gridview as data is not persisting after postback.
i created a user control and place a button on it.i drag dropped the user control on a aspx page and wrote the grid load and button clicks in the
user control.now i got a requirement to use the same user control grid and button to again use on the same page.however the data populated will be different and the button click functionality will be different.how can i reload the different data on the second grid as i had already wrote the code in the first one
I want to show a grid view Control that is initially displayed to allow the user to enter multiple records. This grid view will not be tied to a database nor will it need to save the data that is enter into the GridView Control directly to a database.
I have 2 columns (name and address) in a gridview which are defined as linked buttons. Now when i click on a record in the first row (name) i am able to pass that value (selected name) to another page with rowcommand. Now i am trying to click on the second row (address) on a record but am not able to pass that value to the second page. Don't actually know how to define this in the code below. The first row (name) has to redirect to one page (this what i have already accomplished) and the second row (address) has to redirect to another page
<asp:TemplateField HeaderText="Name"> <ItemTemplate> <asp:LinkButton ID="LnkBtnName" runat="server" CommandArgument='<%# Container.DataItem("Name") %>' Text='<%# Eval("Name") %>' CommandName="go" >LinkButton</asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Address"> <ItemTemplate> <asp:LinkButton ID="LnkBtnAddress" runat="server" CommandArgument='<%# Container.DataItem("Address") %>' Text='<%# Eval("Address") %>' CommandName="go" >LinkButton</asp:LinkButton> </ItemTemplate> </asp:TemplateField> Protected Sub GridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView.RowCommand Dim strName As String = CType(e.CommandArgument, String) Response.Redirect(String.Format("Test.aspx?id={0}", strName, False)) End Sub
CODE ON PAGE II:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load LblName.Text = Request.QueryString("id") End Sub
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
How would I go about displaying a databound dropdown list in a property grid, i.e. a dynamic list that can be used to set the value of an individual property?
have two user controls on one aspx page. UC1 has a grid which contains a link button column which user clicks. Based on the value of clicked cell, I need to show some data into UC2.How do I pass data from UC1 to UC2? How do I invoke a function of UC2 from UC1?
I have a user control that contains a reportviewer control.And I want to send an array of reportparameter to my user control.But I can't figure out how to do.I'm getting "Object reference not set to an instance of an object. ".My param_reportParam variable is null in usercontrol.My user control's parameter is like that ;
[Browsable(false)]public ReportParameter[] param_reportParam{ get { return _param_reportParam; } set { _param_reportParam = value; }}private ReportParameter[] _param_reportParam;
And a simple page that uses user control to show server reports is like that ;
ReportParameter[] parameters = new ReportParameter[4];//parameter number can be different parameters[0] = new ReportParameter("imza", imzalayacaklar); parameters[1] = new ReportParameter("Sayi_Son_Eki", "984"); parameters[2] = new ReportParameter("PersonelTip", "2"); parameters[3] = new ReportParameter("parafli", "1"); wuc_rapor_genel1.param_reportParam = parameters;//this is my usercontrol
I'm dynamically loading a user control from a for loop against a objects collection, eg.
[code]....
I want to pass the following collection into the user control: oPerson.Address[i].listHistory (listHistory is a List of objects which I want to manipulate inside the usercontrol)
How can I pass this into the usercontrol so i can do this
Again, I am wondering why there is no one asking this kind of question. And may be my idea is wrong. Let's see the code:
<uc1:drilldown ID="drilldown1" runat="server" sType="F.W" rID='<%=request.querystring("r") %>' /> After it passed into my property in user control, the value is <%=request.querystring("r") %>
The built in Asp.Net Controls (label, Textbox, etc.) all have a CssClass property that can be set, what do I need to do to implement that for a Web User Control?
I know how to add a property and pass thru the get & set to the corresponding Asp.Net control (example if I have a label I know how to create a LabelCssClass property that provides a get & set, but the control itself how do I set a CssClass or ClassName property.
