Hi Peoples,
I am using crystal report in my asp application.
In which i have design the report separately.
I am loading the report with help of the report document.
ie
ReportDocument.Load("Report Name");
ReportDocument.DataSource(Datatable);
CrystalReportViewer1.ReportSource = ReportDocument;
If my reports page setup is potrait, the viewer is taking the height as
1013px as default and if it is lanscape it is taking 788px as default.
Due to this there is lot of spaces coming in my page.
How to set this report viewer as its height should associate with its report document?
i am using CrystalDecisions.Web Version=10.2.3600.0
and i am facing the same with Version=10.5.3700.0 also
Help me thanks in advance.

First, learn how to format the code you post. Read this How to get an answer to your question[^], its right at the top, can't miss it. Item #7
Look at the section for Checkboxes and Textboxes

I have managed to place a dropdown control iniside a gridview control.
The dropdown does indeed populate in each row...
Question:
How is it possible for the system to correctly select the text in the dropdown based on the value of the field which is driven from the database?
Is it to do with the selectedvalue?
Any suggestions please?
Thanks

i think you use
findcontrol method and find out dropdownbox than conver that control in type dropdown than select value by selectvalue method.
|
|
|
|
|
Yes, but how do I select the value in the dropdown based on the ID in the grid?
|
|
|
|
|
yes you can easily do this thing in rowdatabound event of grid view
RowDatabound event of the grid view and do the code
hope below thing work for you
public void sumRows ( Object src, GridViewRowEventArgs e ) {
if ( e.Row.RowType == DataControlRowType.DataRow ) {
TableCellCollection cells = e.Row.Cells;
int priceTotal = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, _
"UnitPrice"))
//do code to assign value to columns of the grid
}
}
|
|
|
|

I have the following code inside the grid_RowdataBound event. Do I have to delete it and use your code instead?
//Sources dropdown in gridview...
DropDownList ddlgvSources = (DropDownList)e.Row.FindControl("ddlgvSources");
PopulateSourcesGridView(ddlgvSources);
ddlSources.SelectedIndex = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
|
|
|
|
|
no need to delete its fine i think it should work.
but i have problem with this line
ddlSources.SelectedIndex = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
instead of above line you use below one because you are searching with find by value
ddlSources.SelectedValue= ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
|
|
|
|

error is:
Cannot implicitly convert type 'int' to 'string'
To help you find the cause here is what I have at present:
protected void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
//Sources dropdown in gridview...
DropDownList ddlgvSources = (DropDownList)e.Row.FindControl("ddlgvSources");
PopulateSourcesGridView(ddlgvSources);
//ddlSources.SelectedIndex = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
ddlSources.SelectedValue = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
}
//populate the dropdown list of the Sources in the GridView...
private void PopulateSourcesGridView(DropDownList ddl)
{
string strSourceID;
string strName;
int intSources;
DataTable dtSources = clsAccess.SourcesGet();
intSources = dtSources.Rows.Count;
ddl.Items.Clear();
for (int i = 0; i < intSources; i++)
{
strSourceID = dtSources.Rows[i]["SourceID"].ToString();
strName = dtSources.Rows[i]["SourceName"].ToString();
ddl.Items.Add(new ListItem(strName, strSourceID));
}
}
//////////////////////////////////
<EditItemTemplate>
<asp:DropDownList ID="ddlgvSources" runat="server" SelectedValue='<%# Eval("SourceName") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<%# Bind("SourceName") %>'></asp:Label>
</ItemTemplate>
|
|
|
|
|
ddlSources.SelectedValue = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()));
Replace above line of code with following line
ListItem li= ddlSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString());
li.Selected = true;
|
|
|
|
|
On clicking the edit of the row which fires the event grid_RowEditing(object sender, GridViewEditEventArgs e)
then the grid is repopulated and so on grid.databind the error is:
'ddlgvSources' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
Any thoughts?
|
|
|
|
|
this may work
ddlgvSources.ClearSelection()
put this line of code before you are going to select list item
|
|
|
|
|
Not sure what you mean because I click on the edit only without doing any changes and the error occurs just before the repopulation of the grid.
And where do you mean I should put this code exactly please?
|
|
|
|
|
According to me when you are clicking edit of that grid its selecting vlaue in dropdown box again some how so according to me you just clear selection of the dropdown box before going to select for item in it
|
|
|
|
|
Apologies but not sure where exactly in the code you want me to put this...
Anyway, In the grid the cell has a text value and so does the droop down. I would like to match the dropdowntext with the text in the cell of the grid.
So this is what I am doing but the selected text is not selected in the droopdown. Do you see why?
ddlgvSources.SelectedValue = ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString())).ToString();
|

I am breaking down the result so hoopefully it helps you more:
DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()
returns
"Isor"
ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString())
returns
null
ddlgvSources.Items.IndexOf(ddlgvSources.Items.FindByValue(DataBinder.Eval(e.Row.DataItem, "SourceName").ToString()))
returns
-1
please note that I would like the text "isor" to be selected in the dropdown

solved by using findbytext.
Thank you

Hi,
I am unable to retrieve the cell value of the selected row.
The column is set to readonly=true and visible=false
In the grid_rowupdating event
This should be referring to the 2nd coluomn in the grid.
string strValue = ((TextBox)grid.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
The error is:
Specified argument was out of the range of valid values.
Parameter name: index
Any thoughts please?
Thanks

You've marked it as visible=false so the column won't render and thus will not be available.
You may want to look here, and elsewhere, for some tips and ideas
